Mocking someone for their poor decision making skills isn't drama, it's humiliation. Given that we can't challenge people to a fistfight on the internet (well we can, but nothing will come of it) this is the only way to police anti-social behavior.
If someone hits you, hit back. If someone displays anti-social behavior, send some their way. In this way they learn to stop being antisocial. If you bully someone hard enough for being useless, you don't need to ban them; they'll leave or they'll stop being antisocial.
That's not to say that you should go around bullying people for no reason. If someone hasn't done something seriously wrong there's no reason to go off on them. If someone responds to open requests for them to change their behavior then that person shouldn't be bullied. The degree of mockery should be proportional to the antisocial behavior.
What is drama is someone showing up out of nowhere and trying to police others thoughts by claiming it's circlejerking. It serves no purpose other than telling people that they can't let off steam, which leads to tension in a community that leads to more sniping and butthurt.
You get what you incentivize. Provide incentives for the behavior you want in your community. If you want people to police their language so much that it's no longer fun to do whatever your community does, by all means shut down everything that's offensive. I'm sure your forums will be great when it's you and half a dozen other people that all think alike.
RHDN is plainly experiencing a money-grab right now, and the horrifyingly offensive people at BHDN are right that it's self-inflicted and that it will destroy RHDN. It's probably not possible to save RHDN, but there are a lot of talented folks there. Maybe we can capitalize on this and poach some of them that are interested in TRPGs and FFT? If nothing else airing our opinions of the admin's horrible behavior will show that he can't get away with it.
That said, if Xif, the webhost, or the admin needs cash I would be totally ok with her posting a link to her paypal, bitcoin, or monero address. This may bring some heat on FFH from SE, but that's my only real concern. Xif et al. have done and continue to do good things for FFH. No reason there shouldn't be a means to compensate them if someone wants to. Same deal with ads (though I'm not turning off my adblocker).
If RHDN is so concerned about trolls, they should flag troll accounts instead of banning them and charge them ten cents per post. Find a way to make your enemies serve you, instead of wasting energy policing dissidents.
