They probably won't get marked as bad so will probably just stay in the queue unhandled like they are now.
Both the users I mentioned go on spamming sprees. You can review their post history and see them posting a new reply every 2-3 minutes for an hour or two at a time. They regularly open 4 or 5 new topics in the space of 20-30 minutes. I know they are posting more than the usual one line spam of "Bitcoin can make great profits if we just have faith and hold then we have a bright future", but they aren't contributing in any meaningful way. They join any and every thread and either claim bitcoin is dead or call everyone else morons. In my opinion, they are obvious trolls, and at the very least their posts should be deleted. Allowing them to continue spamming seems counter-productive to trying to clean up Bitcoin Discussion, especially since their posts are deliberately inflammatory/provocative and always generate a flood of replies.
I'm well aware of his behaviour and it's obvious he just logs in to post some fud then leave and his only intent is to kick up a fuss and be disruptive, but if you want an answer of how they should be handled then PM theymos about it. I brought the case up about fud trolls and what to do with them at the beginning of the year and have bumped the thread several times throughout the year looking for an answer but no response from anyone let alone admins so I'll assume it's something we tolerate until I hear differently.
