Very recently, Armake21 (a very popular Youtube games reviewer) had his account closed... the details aren't very clear on what happened there but he did not close it himself, that much is certain.
Then, another guy I was subscribed to, Quickening666 (also did game reviews amongst other things), had his account closed as well.
Also, another reviewer by the name of Playitbogart also had his account closed.
And now - the Angry Video Game Nerd has had his account suspended as well! His backup channel too!
I'm starting to feel nervous about my own channel now!
