It is as I've said a legal grey area
As the source images are rarely owned by the poster. They have been caught out on occasion though.

The source images are still owned by someone, though
I suppose tracking down their real owners wouldn't help much.

If the real owner has posted here
and tagged! then they have a time and date of posting an orignal picture that has been seen by many people and that is proof enough for copyright. The actualy person effected needs to take it forward.
