When I was an admin on a site years ago, IPs were our first line of defense. It was a tough tool; in a city, it would be entirely possible to inadvertently block non-offending users. VPN usage was basically nonexistent.
I’m usually on a VPN, just in case you were curious
There are several things I cannot do if I’m using it. Annoying, but I get it.
AI bots were often using forums - on any topic - as a ‘training ground’
fortunately, most forum staff caught on quick and banned them.
there are still some relatively inactive places that are populated by AI-bots talking to AI-bots.
some of it gets pretty funny.

Saw that in a forum mirror (*) (a member made a “.net” copy of a “.com” forum which had a lot of software issues that the admin didn’t have the time/energy to fix, thus a lot of downs). Once the original forum got a new admin the forum was again pretty stable, and everyone stopped visiting the .net mirror, including the member who’d originally set it up.
About a year later I clicked the wrong link and went there by accident. It had something like 30K spam and bot accts, all yammering at each other across the threads.
(*) Don’t know if I’m using the right terminology, but he basically copied all the active threads into his new .net domain.
