Looks like there has been (likely automated, nearly all of them are the same Italian phrase) mechanical legal complaints and it probably caused this instance of automated blocking going wild.
As an engineer I can understand the desire to automate everything, but please at least have some heuristics to detect this kind of easy-to-detect mechanical behavior before giving the model a full authority to block anyone it doesn't like.
Okay, I did some research, and I think I figured out what caused these usenet group banning.
A Genoese lawyer has been a victim of harassing and heavy doxing for some time, you can find many twitter accounts accusing him of paedophilia in cahoots with epstein, berlusconi, the pope and so on (no, I'm not kidding; clearly the stalker has obvious mental sanity problems).
The stalker is very prolific and is wallpapering the internet with his copy-paste-accouse in every corner, from newspaper comments to ancient forums to usenet. The lawyer report and ask for removation where he can but also he does not seem very worried because it seems that this issue goes on from two years ...
I don't think I can say the name of the subjects in question but in any case I'm archiving the harassment accounts before proceeding with the report, then I'll try to get in touch with the lawyer and see if he can request a new, less "coarse" censorship.
I am Italian and this is very interesting: all the requests were made with the topic "Stalking Diffamation Illegal processing of personal data" but this (https://www.lumendatabase.org/notices/21395773) is simply fantastic. It seem that a fool with persecution mania has reported half usenet and the bots was auto-triggered...
