I have a facebook account, as does my identical twin brother. :p
Our profiles are blatantly connected. I was going to say that there were about a dozen friends in common, then I checked and there are 35!
I tend to accept friend requests only if I can figure out where they know me from. I occasionally remove people who have added me but never interacted with me, usually after 6 months or more. It is about social networking, after all, not just collecting friends so that your friend count is huge.
By the way, there are most certainly nudity restrictions on Facebook. They include, for example, no genitals or female nipples. If someone complains about a photo (reports it), it will be checked by a facebook employee and, if inappropriate, deleted and the uploader warned. If nobody complains, the photos will remain even if they are against the rules.
