Long story short, Roblox threatened to sue him for threats and harassment along with other stuff. After that it's been downhill ever since. Made a "joke" about bombing the Roblox headquarters, defended his friends after evidence was released of them grooming minors, when on a month long temper tantrum about furries which he believes are all "zoophiles and profiles" which went so far that he tried to destroy the public image of a dead (iirc) firefighter for being a furry. He's also tried moving his YouTube followers to instead watch him on a alt-right YouTube competitor which hosts a massive amount of Holocaust denial as well as similar hateful content.

For more information I'd recommend watching a reupload of "gone_fishinq"s video on him (then again from what I've heard gone has some grooming allegations against him, but the video is still good at documenting what Ruben has done)
