Far as I know, no one's blocked me yet but now for saying that I'm sure someone probably will. I've only blocked one person, and that was only because they kept spamming me with their badly drawn penis art. >_< Never heard of you before either, but that's mostly because I'm not on complaints often.
I've been added to people's block lists for acting poorly. It happens. But, people are pretty forgiving if you stop behaviors that are pissing them off. I sometime remove people from my own list if I can't remember why I blocked them (it can't be that bad if I don't remember).
