Why cannot photographs be simply for the reason of memories?Not everyone person who clicks them uses them for blog posts and aims for maximum number of shares. If I like particular moment,I would like to click a picture a of it.I would like the picture to be my own ,because I would have a descriptive commentary in my head for the picture.A single location being photographed 'too much' is really not an issue which needs solving does it.I like the use-case which requires the parent's permission for a child's picture.

But apart from that,I see this feature being exploited quite a fair bit.

PS : I am not trying to add destructive comments here.But imagine going on a 20k vacation with a 5k camera being told you are not allowed to click a picture.
