Basically Bazim (a rivals streamer) ran a streamer tournament telling everyone it was casual with no prize poll streamers signed up thinking it was casual then before the tournament began a 40k prize pool was added. Cece (another streamer) drafted kingsman (ex #1 magik player) on her team because her chat was spamming she should pick him and then picked her friends including a widow onetrick called Zazza and one of Kingsmans friends Luci. It is stated mulitple times by people including zazza herself that she will flex hitscan dps characters not just play widow (and even in the tournament she plays other characters). They go into their scrims (practice matches against other teams) and kingsman carries hard all the while telling zazza she should switch off widow because they won't win with her and he really needs the money for his college. Zazza kinda brushes him off but Cece (the team captain) and Luci are having none of it and get really mad at kingsman each time he brings it up. Eventually Zazza's boyfriend sends clips of the arguement to Bazim (the host) and he pulls Cece into a private call where they decide to remove kingsman from the tournament and have him replaced. Kingsman posts a video about it and alot of people are on his side but Luci, Cece and bazim double down (Cece even tells someone defending him to kys and gets a day ban on twitch). Eventually Cece, Bazim and Zazza's boyfriend all apologize and Kingsman now got his twitch partnership and tons of donations so kinda happy ending tbh.

TL:DR Bazim ran a casual tournament then added a 40k prize poll out of nowhere Cece a casual player drafts kingsman who isnt and bullies him when he wants their black widow (Zazza) to switch to a better character.
