I remember reading some time ago, I think via a link on FWR but could have just been a newsfeed, a post by someone who claimed to be successful in disrupting forums they disagreed with politically.
I forget the details but I'm pretty sure one of their recommendations was to just to keep repeating the thing you wanted to be heard over and over and not get involved in trying to answer questions, refute arguments etc. The idea was that it would make your opponents get angry and they'd come across as aggressive or unhinged.
I was thinking today that really only works if your position is rational, otherwise your failure to deal with very obvious questions looks more like evasion or bad faith.
Anyway, I'd really like to read it again to see if that was mentioned, and also to see if I recognise anything else in the article. If this rings bells and anyone has a link I'd appreciate it.
In the meantime while looking for it I did find this :

Not quite the one I'm trying to find as it is from the opposite perspective of recognising when it's being done to you, but interesting to see that forcing the same conversations again and again until people get bored and give up or the forum devolves into in jokes and fails to engage any new readers is a documented tactic.
I've tended to take the view that repeating good arguments as much as is necessary still has value, keeps the turnover of threads fresh and is definitely better than letting bad ones stand (to offer a ridiculous metaphor, when playing whack-a-mole you know the moles are never going to give up but you'll still lose unless you whack them!) but I will think about it.
The "leave old posts that can be reanimated to divert attention" technique also caught my eye because a couple of older threads that I'd posted on popped back to life unexpectedly. I tend to assume it's MN search gremlins rather than anything more sinister (never attribute to malice that which is adequately explained by MN search!) so was interesting to see this is can be a deliberate pre-planned tactic. It would explain why KJK threads seem to pop back to life a lot for no obvious reason. (Then again, I'm not very interested in KJK so maybe it's in response to events I don't know about).
