DRH said it. If people want to "out" themselves they can. If not, then they aren't forced to by your pics. I'd have done (will do) the same thing, unless given specific permission by the pictionee (?).
ps - I call "no fair" to now going back to the FFI pics and trying to "win" the contest

Certainly everyone can ID Pepper's pic !
pps - I don't think the editting was/is controversial. If you had taken a picture of the base of a cell phone tower and smudged the name on the plaque - now that would be controversial !
