Short recap:
It's Kyle Pallo posting behind a secondary account on X/Twitter.
Longer recap:
Around earlier 2023, Kyle was getting a lot of backlash and criticism on Twitter. He'd regularly lash out and call everyone "jealous." It really bothered him as Twitter was the only place where he couldn't delete criticism. The criticism increased until he couldn't take it and he abandoned Twitter a few months.
Fast forward to the Pallo family cruise, his sister Alexa (who had an account on Twitter for over a year solely dedicated to defending him and speaking out against Tattle) had a drunken meltdown where she threatened to get all of Kyle's threads shut down forever. At the same time, a new account appeared and started posting alongside her named "Moose." A bunch of people suspected this of being Kyle because of the same writing style, common usage of words and misspellings.
Another month goes by of "Moose" lashing out at Kyle's critics until Kyle eventually returns to Twitter on his main account and "Moose" stopped posting. Then one day one of his old high school classmates revealed a ton of things about Pallo in high school, including his hatred of anyone who isn't white, creepy obsession with trying to find a girlfriend and what she should look like and wear, and getting caught hooking up with a 12 year old girl in a car. Alexa freaks out and tags Kyle to look at this, and a few hours later another new account appears named "Maverick1Peter" to defend Kyle. Same writing style as Moose/Kyle. This account claims the high school story is all false, while also saying he knows nothing about Kyle Pallo, while also knowing everything about Kyle Pallo.
There was a bunch of discussion on if it was actually Kyle, but at this point it's been confirmed and there's at least 20+ pieces of evidence which indicate it's him at this point. During this 6 months period, he pretended to be 'Stijn Lories' whose some Dutch neo-Nazi and used all his photos. He got busted, then said he was trolling. Then went back to being "Peter," then stole one of his critics identities and photos, now he's back to being "Peter" again.
Like Kyle, he has a huge ego, obsession with himself, constantly praising himself, hates all other Disney vloggers, posts all kinds of sexist/racist/homophobic rants, uses a lot of Disney GIFs, thirsts over famous brunettes like he used to do on his main account, searches for his name on X every night and seethes at anyone talking bad about Kyle. I think he has around 1,500 posts at this point. There's a lot more details and story behind it, including all the evidence, but it would take me a while to recap it all fully.
He's constantly changing his username and deleting posts when he gets caught or called out for being Kyle, but his username now is BasedPete13
