I think ATW posted a sort of "farewell" post on twitter to tell why he was gone. It seemed that he was originally self-exiled and then eventually banned. I think he claimed that there was some exchange between him and Clutch behind the scene. I don't recall Clutch telling his side of the story.
He wasn't banned. He stepped away from Clutchfans. When someone mentioned he was banned at the time, I made a post asking what for incredulously, because I didn't want one of the only other Sengun realists from the early days gone. It was hilarious always seeing the new stats ATW would always post which constantly proved how good Sengun was. He then messaged me and said he wasn't banned, but rather stepped away to focus on other ventures in his life.
It wouldn't surprise me if he had something else going on outside of CF tbh. Towards the end he was even attacking the other Jalen fans a lot of the time, it got pretty wild.
If that’s the case I wholeheartedly support his choice, Clutchfans is supposed to be fun and if him being on here was taking time away from actual important things he had going on, stepping away was definitely the right choice. I do miss his constant stream of Alpi, though. I actually really enjoyed them
