if you have a problem, block it
We dont have to like the sigs, but if they are within the boundaries of the rules, than I support them. Just because you or a small group doesn't like them, doesnt mean it should ruin it for the rest of us.
Nudity is something completely different, and if it were posted I would be angry. But as long as there is no nudity, then I have no problem.
And if two semi-naked dudes are getting their almost sexy time on bothers you, just block it. You seem to be more angered at the fact you see two naked guys than a bunch of half-naked chicks. They both are allowed, neither is worse than the other one.
