fairly petty civil actions

If you're the person having their reputation smeared by anonymous cowards it maybe doesn't seem so "petty" as you dismiss.

This seems like a perfectly reasonable thing to do; have the person slandering somebody anonymously brought into the light where there is a level playing field in which they can present their case.

I'm not sure it's creditable that enough credence is being given to these anonymous claims in a private group to be impacting this person's life. Seems more akin to a slapp.

How many careers and lives were ruined by the anonymous "Shitty Men in Media" list?

Some cases were probably well desreved, but anonymity allows easy score settling and revenge.

There's no recourse against an anonymous accusation, there's no way to defend yourself, and there's no way to prove you are innocent.
