Why do people care so much and get upset over other people's avatars and sigs? I've never had a single problem with either in my 5 1/2 years as a member.
Like others have said; if you're browsing this site at work or school, shouldn't you be doing your job and/or studies? And if you're ashamed of browsing the site with your friends or family around, you're either paranoid or they need to calm the hell down.
Can you read a tabloid magazine or a fashion magazine? How about newspapers? Scantily clothed people appear in these all the time (especially tabloids). I just had to check to confirm my suspicion; you're from the US, things like this are often blown entirely out of proportion in the US, lighten up people.
And if your girlfriend can't understand what the site is about upon actually seeing and reading the content and gets hung up on the avatars, she has a problem. Is she illiterate?
Messaging other users to make them change their avatars is childish and extreme in my honest opinion.
