If you let people take pictures of you or what you consider private, it's fair game, I'm afraid. I have a facebook page, but no-one really comes to my house as it is my sanctuary. Because of trying to escape abusive family, hubby and I have moved twice and do not advertise our whereabouts.....and that includes internet profiles. If your friends are offended, they should ask for the posts to be removed and not partake in such activities again. I don't, however, understand offence at such actions.....
