1. Get banned for a made-up reason X in publicly viewable modlog, without right of reply or recourse.
2. Get doxxed and username tied to your real world name.
3. Doxxers send screenshot of you being banned for X to employer.
4. Employer fires you for irresponsible use of social media.
5. 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 anyone would take the risk when a generic reason will suffice or simple insult would suffice is beyond me.
