I don't know about that lol, sure, some people probably come to troll. However, others like me who are longtime members of the Unity community, but first time members to this server, came here because we saw something online happening in a community that we care about and now we're here to show our support for all of the people who've been banned lol.
After reading through all the drama and seeing the dozens of bans I'm fearful I'll be next just because I haven't been active in this discord before. I feel I almost have to specify that I'm a community manager of a decently sized unity-game dev community discord to justify my connection to the engine lol. I don't think we want to gate keep any more than that.
Also, a flood of users isn't exactly a bad thing. I'm an active member of the Unity community but wasn't in this discord before seeing an article online about it. There's pros and cons and it seems like the moderators are pretty on top of banning spammers anyways lol
