I mean, I understand why Lunar was banned. From what I've heard, he's a fuckin' social retard who can't take ques, read a room, and doesn't know when to stop. If he's being a creepy weirdo and someone says he's being a creepy weirdo, rather than just stopping, he'll double down and go "no, I'm not a creepy weirdo. This is a hill I will die on, lets argue". Then some mod will show up, shoot him and it's like "yeah dude, good job. You died on your hill. Now we all think you're a fucking weirdo." If he conducts himself offline like he does online, he probably makes people uncomfortable and won't stop. Not that I have personally interacted with him, but I play fighting games online, so I see him in discords and I've seen some of the exchanges between him and other users. I'm sure many of the people who are involved in this are just as big of retards as Lunar is, but what seems to set him apart is his inability to just shut the fuck up and read the room.
That being said, the organizers who handle bans by just releasing a picture of text then turning comments off and never elaborating are also retards. I wish organizers would just be more up front with why they're banning people. Not link lame ass vague ToS or just call someone "problematic". If the only reason someone gets banned is because the organizer personally doesn't like them, that's fine. It's their event, they can choose who can attend. Not elaborating or just being honest does way more harm than someone not playing at your venue because you made it public that you dislike them. But I guess that's the point, it's supposed to be harmful. If they really just wanted to deal with the problem, they'd confront the person, be transparent, and deal with it like an adult. Not make a gay twitter show over it.
