Bad faith actors are a thing. But in both of these cases, the system were their enablers. In America, the right leaning judicial system are basically looking the other way while red states ban abortion and suppress voter turnout. In your case, the admins of that site even made that poster a moderator and I am pretty sure they even banned people who criticized him. I think it really shows that there needs to be further accountability within these opaque systems. Several justices on the Supreme Court such as Thomas have connections to right-leaning organizations such as the Federalist Society and yet they don't recuse themselves when there are conflicts of interests. I think the same is true once you go further down the judicial system.It reminds me of a Trek message board from back in the distant past of the early 2000s. It did its best to be fair, transparent, democratic, all that. The rules were clearly spelled out, all warnings and bans were public, and there was a public forum to appeal such.
Unfortunately, it didn't work. There was one user in particular whose sole purpose in life was to get his post count on this board as high as possible. So he'd double and triple post, reply to himself, bump old threads, start new threads. And every time, enough people would complain that a new rule had to be instituted. 'No double posting within a certain time period.' 'You can only create a certain number of new threads per forum per day.' And so on.
The board was never willing to institute a basic rule, a rule 0 to say 'don't be a dick'.
