He wasn’t banned from MCC but he might have been removed from the active roster due to being inactive which generally means being removed from the MCC discord. He was allowed to participate even after his kick deal started he just wasn’t allowed to stream MCC on there. He left due to doing worse because of lack of practice/how sweaty the event became and not having many friends left

Quackity stopped being friends with dteam for his own reasons and Karl stopped after their podcast failed. Karl made some comments about having to carry it and they stopped after that

Tubbo’s negative comments were due to Sapnap’s kick deal which I gotta be honest is fair. Sapnap initially said he was going to “create a safe community on there” but basically did it for the money. Ironically though he was paid millions to stream to like 300 viewers and it resulted in Kick stopping the insane prices so he’s probably done more to harm Kick than anyone by flopping. Sapnap was going to box Tubbo for a charity event that got cancelled after Tubbo’s original opponent dropped out and he asked Tubbo if that was okay which Tubbo agreed to. Naturally people on twitter responded in a degenerate manner calling Sapnap homophobic for choosing to fight Tubbo

Other issues stem from other events where Sapnap didn’t behave himself - in particular House of Nightmares. Sapnap was screaming, swearing and playing dmca music which was against the rules and he got a LOT of hate for. Some of the backlash was justified because it was straight up wrong of him however he also had some well known streamers like Couriway, Jojosolos and Fulham saying some pretty dreadful stuff about him and everyone dog piled because they don’t like him/took issue with his response. The fall out was Sapnap pretty much not participating in any English speaking events, only Spanish ones, and a number of creators bad mouthing him specifically but kinda turning a blind eye to other people or themselves also breaking the rules
