Good point on the R threads. I had hinted those threads were comped.
When Q arrived I don't think you were this swamped with shills. I've been on forum rife with mil-int shills and I've never seen as many as those on Q boards. Even the shills who aren't on 8chan are yapping about Q (on forums that don't even discuss the topic).
They're doing both active subversion here AND pre-emptive 'damage control' here.
But I concede your point. It's always difficult to determine when to apply censorship (I won't couch it as 'moderation' because there's no such thing as 'censorship in moderation').
But will you be able to bare out the full brunt of the intel agencies+media+paid corporate/political shills? If you give them too much breathing room they will literally 'nuke' a forum by filling it up with trash (by having bots, constantly rotating IPs etc posting continuously).
Google offers a service that can solve the captcha you provide here. Not even Google's own captcha uses the letter-captcha and they don't advance their captcha until their own bots defeat it (why do you think it always involves 'roads'? Google's latest car AI project in a nutshell. Before then it was books with the words. How do you think they traniterated so many books?).
You've got all the signs of an incoming shill shitstorm. If I'm here (I go where-ever the currents take me), then there's a shill shitstorm that's about to break.
I always somehow end up on the frontlines just before it does.
I'm working on a tool but my resources are stretched at present, so if they do hit, censorship might be the only option you've got. Believe me, you've never gone head to head against a machine that can post hundreds of threads a minute.
Shills don't need to convince anyone of anything, merely destroy what you already have.
If you can't censor, then find a way to filter the posts so you only get quality. Q would have been buried years ago if it wasn't for the likes of qanon.pub where the posts are isolated out.
