I try to do the same, but sadly without seeming rude and asking friends to remove you from photos or leaving you out of messages, you leave it to chance.
For instance, I've never put a photo of myself online, yet Facebook has me tagged well over 300 times from going out to bars with friends. I'm ok with my friends seeing these since they actually know me, but I can't control the privacy settings on their albums -- only whether or not people can get to those photos from my page.
I don't walk around with the uneasy feeling that, at any time, I could be photographed and unknowingly put online... but I still think about it from time to time.
