If someone was viewed as a spammer, then all of that persons posts would be deleted.It doesn't mean that the thread you saw them under would be too. So basically, even if they did have what seemed to be a "quality post", if you get labeled as a spammer, ALL previous posts are deleted. Trust me, I know this, as I was incorrectly labeled one, and got all previous posts deleted. However, they are trying to protect the integrity of the freerolls
they offer, so you can't blame them for being vigilant in spam-busting... even if they get a little TOO vigilant.
