Seems like a huge gray area, like so many other things. What's the difference between "shitposting" and "trolling" even? I think it'll be unproductive to get further down into the weeds of what kind of shitposting crosses the line, and what doesn't (like so many others here, I'm drawing from my own prior experience as a moderator
). If jking thinks a user is intentionally trying to derail the thread with spammy posts or flamebait, then he'll take action to prevent that from happening. If it's more borderline, or perhaps an honest mistake, he can nudge them in the right direction with a pm and take more serious action if the behavior continues.
