Apparently from what I understood he might have hit a really big infringement against Twitch's policy and Twitch doesn't seem to be letting up on his bans. There are a few 24/7 streams, one of which I know got partner approved. Guy just plays random corresponding game videos on his stream while he sleeps and games for a few hours while he is awake daily.
Another is a purely drops channel. But both did not offer any physical rewards the way hitsquadgodfather did and maybe that reward itself infringed Twitch's policy? Otherwise I really can't think of any reason why the other 2 are still standing while hitsquadgodfather got banned. Maybe his way of reward enticement to attract massive viewers in exchange for higher ad revenue didn't sit well with Twitch or it's advertisers? Who knows?
Still it is a really sad thing that he isn't able to stream anymore
