This is kinda outing me as a "current-thing" lurker I guess, because I don't know if this applies to the wider Thunderdome board culture or not and I'm using it as a bit of a case study, but I like the kind of two-state solution that's emerged with the Ukraine threads where both sides got their own corners to have their pro/anti Russian postings, and occasionally a vatnik comes into the MSM thread to piss up the wall and vice versa. Usually when that happens its bad-faith sperging though and kind of sours discussion.
In this case, clamping down on that kind of combativeness by banning them out of that corner would probably improve quality of discussion, but when you prohibit people from shitting where they want it does bring about the hugbox accusations and makes it look like threads have to keep to consensus opinion or the jannies swoop down.
I think in this position where discussion quality is the goal, I would let the hugbox accusations rain in and just threadban people coming in to shit on the thread's consensus. I don't think this necessarily means the consensus should be never be challenged, if you have a good-faith case against someone's opinion that's something that should be posted, but when you can clearly see some fuckin retard is rolling in just to stir shit up because he sees the posters there as ideological opponents or something, they should really just fuck off. I guess it can be hard to differentiate the two sometimes, but there is definitely a class of Thunderdome posters who just aggressively seek out opinions they disagree with in order to be combative and I feel like a good mod would be able to identify these people and treat them accordingly when they come into a thread with no other clear intention than to shit on the floor.
NOT volunteering btw, janny work sounds like hell and I have under 30 posts and mostly just lurk so its entirely possible my position on this is tilted. Too busy to sweep up full time, too.
