Geektastic: Not actually ever having taken any, this would be one thing I can safely ignore!
Ah, but that's not the issue. The question is: Have you ever *had* any taken?
Of course, if they've been taken without your knowledge, or you don't have a copy, then you're still screwed.
Maybe FB should apply their face-recognition technology to this, so you could ask that any photos with your face on them not be shared by your ex. Wouldn't help if you had particularly recognisable pink bits though. And lots of people who would recognise them.
