As Facebook users cannot help being tagged by others (although they may un-tag photos), Facebook photo whores are most accurately identified by having more or an excessive number of photos tagged by themselves rather than tagged by others, indicating that they either have no life and no friends to include them in photos, or carry around a camera constantly, indicating that they probably have no life and are weird and desperate.
B: No, dude, 487 of those were posted and tagged by herself.
A: Yeah…and she's shitfaced in every one of them. What a Facebook photo whore.
A: Man, I love my roommate, but almost half of her photos were tagged by herself. Do you think I should say anything?
B: Yeah, I mean, I wouldn’t want people thinking I was a Facebook photo whore. Or that I was hella lame.
