That was when the channel initially got banned a month ago, this article is about how it's back now.

GP mentioned that the content of the stream today is very different than it used to be, likely due to legal issues.

That is accurate. This is incidental to the changes in the format, if you've seen the new version. Instead of the characters clearly impersonating Seinfeld in the scene composition eg a man doing standup, shots of the building, internal postures, visual character similarity, music, it's a specifically changed show. I observed a random set of persistent characters making less smooth random motions and strange ML-generated insets to replace problematic scenes, and no music. The language and clarity of speech is a lot better now.

Is making trans jokes a bannable offense on Twitch or do they have a loose policy where they can just ban you for whatever like YouTube and Twitter?
