Crazy that people do this kind of crap. I've reported a number of them already, my successful report % doesn't seem to be going up though which is weird.
If a mod handled your reports and it turned out to be a spammy, off-topic or nonsense post, then your % might increase.
Well there are also different kind of spammers out there, specially those recurring "FREE 0.5 btc BONUS!" threads on different boards which is pretty annoying. This one is daring, posting a link with a malware is a no-no in this forum and should be banned.
