That brings up an interesting point. I'm sure the majority of fen don't seek permission from rightsholders before dressing up as someone's trademarked/copyrighted property, so the idea of picture-takers needing to ask permission is probably (legally, at least) somewhat of a grey area.Is she talking about subjectively creepy pictures, or is it the general expectation that every time you take any picture at a con you request permission of the subjects before you take it?
