10/23 was the members stream where Vesper mentioned he was banned from turning off superchats. He said it was for 6 months from that stream where he panicked an turned them off, and they'd reevaluate the ban after the 6 months.
11/4 was the members stream where Vesper turned off superchats. (Edit: Vesper did not do a members stream last week, so the 11/4 stream is currently the latest members stream.)
He's talked in multiple members streams about being able to get away with things because management isn't able to view them. His tone was tongue-in-cheek, but maybe the ESL JP middle managers didn't catch that.
