"Twitch claims their policies haven't changed."
Big Tech companies (#Twitch is owned by Amazon) often have two sets of policies. A vague public set of "guidelines" which are there to justify a decision they've made.
And then, there are the more detailed internal policies which are distributed to moderators.
I can't speak for Twitch specifically but there are other companies which are like this.
And hey, I think their rules are silly and censorious, I'm not defending them. #anime
