Here's the single-most wildest idea ever: if there's a topic or post that you don't like, perhaps made by someone that you don't like even, then just ignore it. It's that simple. Stop falling for the bait and stop getting easily provoked by the stupidest shit—because I will be brutally honest here, out of all the forums I've been a part of in my time on the Internet, this has got to be, without a doubt, the one with the most thick-headed members I've met when it comes to dealing with trolls and spam posts. Trolls can be a nuisance, that's a given, but even worse are those of you that take the bait hook, line, and sinker, keep poking at the nest, and then wail like babies when they get stung. Trolls can be a problem, but you're as equally culpable for continuously falling for their games. Granted, there are ways to circumvent things like this from occurring, but unfortunately this place lacks a bunch of features I've seen in other forums, like the option to ignore users, which effectively blocks everything they do around the forum that I feel would be a nice band-aid for this kind of situation.
Seriously, for your sanity's sake, just learn to ignore and move on.
EDIT: Just so we're clear, this is a broad statement, I'm not directing it to OP or anyone who replied to this topic. In other words, to whomever this shoe may fit, wear it.
