Allot of people are wondering what happened to One Angry Gamer owner William Usher, aka: Billy D, as his site was seemingly sold to some corrupt regressive leaning assholes before he wiped most of his online presence.
My theory was that as his site hosted the traitors of America list that outed several companies for promoting regressive leftist propaganda, focusing on cases related to defending the 2020 regressive leftist riots in America, he had attracted a particularly nasty regressive leftist harassment campaign that spammed the UK police with both hate speech complaints as his site was heading into the direction of /pol/, and allegations of CP law violations that may or may not have accurately indicated they were related to lolicon.
Thus he may have gotten arrested and made a questionable plea deal to avoid both being stuck on the registry over lolicon, and getting thrown in jail where he may be rendered vulnerable to abuse by prisoners and staff either for political reasons as he hates the regressive left, or due to false pedophilia accusations related to artwork.
Will usher was also noticed to have indicated he regretted selling the site before he closed his twitter account.
TL;DR: Billy D may have taken a plea deal to dodge illegitimate sex offender registration and abuse in prison and that's why the site was sold.
edit: Another theory is that he took it down and sold it because some regressive leftists found out about prostasia's views regarding pedophilia and threatened to smear him because he promoted it by mistake while defending lolicon, though honestly he should just come out and apologize if that's the case.
