Get banned for made-up reason X in publicly viewable modlog, without right of reply or recourse.
Get doxxed and username tied to your real world name.
Doxxers send screenshot of you being banned for X to employer.
Employer fires you for irresponsible use of social media.
Sue for libel and damages (lost revenue from prematurely terminated employment). Chance of winning probably zero, but a bored no win no fee lawyer, or someone with too much time/money won't care about that.
All quite implausible, but why any mod would take the risk when a generic reason will suffice or simple insult would suffice is beyond me.
It's similar amateur hour shit here on kbin. You can ask to have your account deleted, but it won't happen. If I was a dickhead, I could file a GDPR complaint. You only need to rub one arsehole the wrong way, to open yourself up to a whole load of entirely unnecessary bullshit.
