Stalking behaviour, threats of violence, racist and sexist comments (regardless of gender/race) or otherwise severely insensitive comments with malicious intent, homophobic comments, transphobic comments. It really doesn't matter who is the victim. The video was criticising b4nny's behaviour and not his person. I don't think se7en should have posted that video, but you've applied no nuance to the situation and you are comparing someone who got harassed unprovoked after opening up sexual abuse to someone who got criticised for being toxic to another player. Do you think a shoplifter should get the same punishment as a bank robber?
I agree with you on when harassment starts, but you sadly still imply that the video is meant to criticize b4nny, when it is not. It is what you would categorize under "Stalking behavior" and "comment with mailicious intent". You don't release a video like that if you intend to criticize someone, it is not constructive, nothing, it is simply clips cut together, all b4nny clips in less favorable situations to show people "See this guy you like? He is a fucking asshole". Also remember the context, they had fat beef during that time and you surely don't criticize in a constructive manner when you are angry at someone else. Don't fool yourselves, I could take a rapper dissing another rapper and reduce that to "It's actually just criticism, chill bro"
B4nny video aside, what about the Credu situation? How is that any different other than that racism was applied indirectly instead of directly? Do you think apologizing just solves this problem? Saying "Sorry, we already have taken action and removed him from the roster, please dont punish us" makes this all okay? They obviously had no power over Credu, just like the punished team had no power over Pred, so do you think it is fair that one team gets off scot free while the other doesn't? How come Pred's entire team is punished, but all of Se7en might be left unpunished?
Do you think a bank robber should receive a perhaps lighter punishment just because he apologizes for it or has a good reputation within his community?
