Jessica Yaniv Simpson’s messages to the world as well as to individual girls and young women he has targeted over the last 12 years attract critical attention because they often display pedophilia, which he denies but continues to display. Preventing the documented types of harm pedophilia does to minors is, of course, of paramount concern for everyone.
When MeowMix sifted through Yaniv/Simpson’s messages to 10 girls and young women sent from 2008 into 2020, we found a very consistent style in his approach. He talks about his need for pads because of one health problem or another, expresses fear that someone will notice he wears pads, complains of gut pain that he calls menstrual cramps, hectors girls into coaching him on how to hang around in girls’ restrooms and change rooms, wants photos and items of their clothing, tells them he wants penis-in-vagina sex with them, and sometimes says he wants to marry them.
When looking at those messages, what jumped out at us was the prevalence of traits associated not just with pedophilia but with other paraphilias, two of which are frequently commented upon – autogynephilia and menophilia – and two of which are ever-present but seemingly too obvious to draw much comment – voyeurism and exhibitionism. We even noted traits of autopedophilia, that is, finding sexual arousal in imaging himself as a small child, that is, a sexualized small child (as in his Elmo messages).

In a separate project, we had gone through MeowMix’s extensive image and document libraries to collect Yaniv/Simpson’s words for the “Quote of the Day” feature now added to the site’s main page. That collection of 300 quotes from Yaniv/Simpson’s messages and posts since 2008 coincidentally showed us that half of them (149 to be specific) showed traits of the same five paraphilias:
- Autogynephilia – 45 of the messages (30%)
- Menophilia – 34 of the messages (23%)
- Pedophilia – 29 of the messages (19%)
- Exhibitionism – 25 of the messages (17%)
- Voyeurism – 16 of the messages (11%)

A special note about the 19% figure for pedophilia: All of Yaniv/Simpson’s messaging with underaged minors could well be counted as pedophilic. He messages these girls purely out of his attraction to their youth and purely to lead or badger them into sexualized conversations and actions to gratify his pedophilic needs.
For purposes of our analysis, however, we categorized messages by what was stated rather than by the intent behind sending them. Consequently, we categorized messages as pedophilic only when Yaniv/Simpson commented directly about the desireability of an underaged girl (to a 13-year-old, “i find u extremely attractive lol” Riley 9) or tried to steer the girl into sexual activity (to a 14-year-old, “EW FUCK I JUST OPENED KID PORN EWW … wanna see?” Ashley transcript, p 6). He was that explicit in about one-fifth of the 300 messages and posts we compiled for Quote of the Day.
People with paraphilias do not segment their drive for sexual arousal, so not surprisingly, 71 of those 149 paraphilic messages we examined were blends of two or three of Yaniv/Simpson’s fetishes.
- Menophilia/Voyeurism: To a 19-year-old: “so are u on ur period right now?” Twittergirl transcript p 41
- Exhibitionism/Pedophilia: To a 13-year-old: “How can I bond with these girls from the swim team? I usually turn myself towards the locker… I want to face them to change” Riley13
- Autogynephilia/Menophilia/Exhibitionism (tweeted to the world with a picture of himself at a pool): “My period started so ya, couldn’t go into the pool… Forgot my tampons…” Voz3
All of the above transcripts are in the Chat Logs folder in the MeowMix Document Library.
In at least one case, he managed to cram four paraphilias into a single message to a 13-year-old: “girls your age are getting naked with their friends, fully naked, and smiling at me while I change as well” Riley21, which combines pedophilia with voyeurism, exhibitionism, and autogynephilia in only 20 words.

What else can we gather from studying these patterns?
A correlation exists between voyeurism and exhibitionism, so the idea that Yaniv tries to commit both voyeurism and exhibitionism in women’s spaces may have some validity. Yaniv needs to intrude in these spaces to satisfy these cravings.
Exhibitionists are often hypersexual; that is, they have a dysfunctional preoccupation with sexual fantasy, often in combination with the obsessive pursuit of casual or non-intimate sex, pornography, and compulsive masturbation. If I added a hypersexuality column to the paraphilia frequency table, every victim’s row would have four dots in it.
Prof. Ord Matek suggested that exhibitionism demonstrates expressions of aggressions, a desire to exhibit power and control, and a desire to gain recognition. The DSM description of Hysterical Personality Disorder includes exhibitionism in its list of behaviors. This will be explored more in future MeowMix articles.
Yaniv appears to be primarily driven by hebephilia, a subgrouping of pedophiles who are aroused by pubescent children, aged 10-13 (girls) or 11-14 (boys). When he targets older girls or young women, he sometimes states that their appearance strikes him as that of a 14-year-old or they note he has found photos online showing them at age 14 or younger before messaging them at any length. In one instance, he told 17 year old Madison that she looked attractive in an old picture of her – one that she told MeowMix was from when she was 11 or 12,
Hebephilia correlates with differences in brain structure, which may mean that a factor in its development is disconnections in brain networks that recognize and react to sexual cues. Although correlation does not equal causation, since we know Yaniv was born with one or more neurological abnormalities, it may be worth reading further about this correlation.
We don’t know if Yaniv ever dresses like a child as Stefonknee (Paul) Wolscht does, but he does filter his pictures and voice to appear and sound younger. The picture below show Yaniv stating that he wanted to appear like the young girls in the photos.

He clearly exhibits pedohebephilic behaviour and studies have found that nearly half of all pedohebephilics also reported being autopedophilic, and 32% of those reported autogynephilia. The study stated, “…autopedophilic men sexually attracted to girls are likely to find it sexually arousing to imagine themselves as a girl.” and “Sexual attraction to 11-14 year old girls was most strongly correlated with sexual arousal by the idea of beig 11-14 year old girls.” You can read more on this here.
MeowMix will dive deeper into these individual behaviours over time but the information above clearly highlights Yaniv’s pattern of behaviour. It’s the same things every time – sometimes even the exact same sentences. Try to view Yaniv’s behaviour through these lenses. When he tweets about a pageant, what is driving him? When he posts a filter video with mouse ears, why did he do it? Nearly everything can be traced back to these paraphilias.

Fantastic job you guys! I love this article!
An angle to look at regarding autopedophilia could include his obsession with music that would have been popular for girls around when he was 14/15 – teeny bop type artists like Hilary Duff, and Avril Lavigne’s first album. And then there’s his obsession with things teens these days love – like those LED strips he told Sara he wanted to have in his room. What grown 33 yr old (man or woman) wants LED lights in their bedroom like it’s a rave?
Great article. Looking forward to the follow up articles
The Lone Gunman nailed it!
There’s one thing you don’t do in life and that’s prey on children like Yaniv is doing. This is why people would like to terminate Jon’s life. There’s no rehab for him, no medication that will help him not prey on young children. They need to bury him in an unmarked grave so the world can forget he exists. His victims would feel safer.
When you make comments like “terminate Jon’s life” you lose credibility. Take it back to 4chan.
Yeah, you’re probably right and I do take that part back.
This guy has caused so much carnage to people, ruined so many lives that its frustrating to see him try to force himself to be in situations where he can expose himself to little girls at the beauty pageant.
Why do people like him exist? Jons the most disgusting person on this planet.
I’m gonna have to disagree with you that JYYS has ruined so many lives and has that kind of power. Yeah he’s kind of dangerous and yeah he’s unstable and yeah no he don’t have BPD he Has Anti Social Personality Disorder scoring high on Narcissm and lower on Psychopathy and Sociapathy. Don’t know who is diagnosing him but had they been following the story like we have they would take the BPD of the table.. so yeah while he has been toxic to many young people and his own mother and lord I hope those animal stories are not true, I’m still gonna disagree cause he’s such an IMBECILE he causes everyone to see RED Flags right away or not too long after, that he blows his chances for further manipulation. The young women he’s repulsed and traumatized have their whole lives ahead of them to heal and it’s not like he actually got close enough to rape any(sure hope not), drain their finances or breed with them. Except the last catfished woman Rachel, who did what lots of us women have had to do to get him the feck out of their homes safely. And the other catfished women who met up as well. These women more then likely have loving family and friends as well to get them through their past ordeals with JYYS, not every woman is a delicate wallflower unable to cope with any thing traumatic and unable to move on with life. I’m speaking here as a survivor of a traumatic childhood caused by APSD And other stuff, whose witnessed many lives actually destroyed from a person who once held a lot of power. I’ve seen the aftermath…Also the one person that does concern me alot that may need actual help is Manda. I worry her home life must suck real bad if she actually thinks JYYS is someone worthwhile to be friends with and actually wants to see him in person or may have. Is there such horrid things going on in her life that JYYS with a condo and a car is someone she thinks is a better option and she wanted to go there? Please wake up girl you are worth so much more then JYYS. I hopr you have a good life and I’m worried for nothing.
Might want to take a peek at @ItsStillMaam1 on Twitter. This user is currently reporting about Yaniv targeting its niece in a bathroom stall.
If there is evidence of this supplied in any form, this will be all that’ll be needed to finally get Langley RCMP to deal with Jonathan. I’ll be watching this for more developments.
This article is the exact reason Yaniv needs 24/7 supervision, he is impulsive and cant control himself, if this new claim is true that he tried video on a 12 yr old in the bathroom, his PO needs informed, and he needs to spend a long ass time in jail. I dont know how much more warning RCMP need about how violent he is, hes a timebomb.
Thank you Lone Gunman for this brilliantly researched, written & graphed article. It is one thing for everyone to bring up episodes & examples of Yaniv’s behaviour which he can & does dismiss as lies or just plain, old transphobia created by his enemies to ruin his life (as if he were that important). To date his outraged denials & protestations of innocence have mostly worked with the legal system because they have been dealing only with specific examples without context or seeing the WHOLE picture until now. The only context they have had to work with has been Yaniv’s version of events, falsified evidence, & claims of being a protected class deserving of special treatment & protection from such obvious hate. You have laid it out for them in any easy to understand format which totally demolishes Yaniv’s claims & manipulations. Law enforcement & his victim’s lawyers can now compare victim stories, dates, & actions against Yaniv’s version of events without having to deal with the extraneous political correctness overlay to expose the truth of his child exploitation.
Beautiful work that will help the police and researchers in the future, plus when Yaniv denies he’s a paedophile or has ever done anything wrong we can simply refer him tho this article.
See how ill you are John? There are graphs pointing it out but I know you want the “simple look” being a girl, but it turns out that you are probably too much of a fucking simpleton to understand how dangerous you are to children even after looking at the colored pictures, so you’re half way there, now you just have to lose about 200 pounds and take 18 years off your age of 33, actually you look about 45!
How’s the plans for Jacks’s headstone going Fat Jon the fake Tranny? How much did it cost and when will it be installed? What, you don’t give a fuck? I think we all knew that, tampons, dildos and new cars come first eh Jon, fuck Jack, he was a cunt in your eyes anyway, you’re far better off fucking your mother, which reminds me, nowhere in this article did they mention incest? Love!
As with Ontario there have been many cases 0ver the year where males feel they should be allowed in women only spaces each time they lost.JV will find Ontario is not going to be a easy Province for him to get support be it media or supporters.
Along with everything else our favorite nonce is SO delusional and UTTERLY lacking in self-awareness.
He wants to look like the young girls in the photo: that is the look that he is going for.
Never mind that he is (a) a man, and (b) thirty-something years old. IN fact it is (c): the fact that he weighs probably over 300 pounds now and has at least four chins, that really underscores how entirely and completely divorced from reality this clown is. He really believes that somehow a hideously ugly land-whale can achieve the look of a 12 year old girl.
As has been observed by others, it is really fortunate for society that his i.q. is so low. Imagine someone with his morality/drives and YOUR i.q.
Scary.
