Generally, I don't accept friendship from those who do not post their profile picture, or if I suspect that they have posted a picture of someone else ( an actor, boy pretending to be a girl or vice verse, or something silly or cheeky etc). IMHO we should be wary of such people because it's not just the shyness, but there's something such people need to hide...It's just my opinion...but I don't feel very comfortable accepting such "living" people who are hiding their identity -so to speak- as my friends...
