Re: Would this bother you?
I think dad needs to help with this and cameras, phones, and laptops/tablets need to be off limits at this house until it has stopped completely. My guess is the daughter sees the no pics on FB rule as stupid and she probably was sneaking him into the bathroom so she could post a pic and not get caught (not so smart). I doubt she understands what that is implying and although she is deliberately disobeying she may not understand to what extent she is causing issues. Many people post pics on FB without a thought. I bet she just doesn't see what the big deal is.
