Bullshitting aside, QRD on this @whatsupwthat ? I'm vaguely familiar with this kusa guy, but I thought he(?) was making unofficial con merch. I guess it's an ugly look to be fighting with enthusiastic fans, if that's actually what happened.
Sure.
This all went down when a cosplay thot decided to do one of those engagement bait posts on twitter, saying that she'll cosplay the person suggested in the most liked reply. Kusa replied with a picture of Sakana but the cosplayer hid the reply and pretended like nothing happened, and chose a less liked tweet to cosplay.

She did the same with others suggesting vtubers, and blocked them, Kusa and anyone who called her out for hiding the replies. After enough backlash she deleted the tweet and privated her account. As a response, a different cosplayer also made a poll on which character to cosplay, using this controversy as a way to shit on the original cosplayer, and Kusa suggested Sakana there as well and it won.

Kusa would use this opportunity to flex about how he BTFO'd the first cosplayer.

Some time after this, Lia would block Kusa for an unspecified reason.

And now, in yesterday's cooking stream Shiina would go on a rant about this situation, vaguely referencing "Phase fans harassing cosplayers for not cosplaying Phase characters" and said that the talents are forced to "not represent" their creations because of such behavior. Timestamp 3:20:17
Doesn't seem like it's a company-wide ban though since Kusa was interacting with Pippa and Jelly before this stream happened.
It all just seems like a very bad look, because you have others like Luwud sexpesting everyone about Phase and he goes unpunished, but Kusa gets ostracized over the smallest controversy that he didn't even start. Sakana wasn't the only character she refused to cosplay as, and she hid the replies of a lot of people, and that's mostly the reason why she got shat on.
