I post things on here that I find funny but don't take credit for them. I wouldn't expect anyone to give me rep for finding something funny that someone else produced.
I think the most you can say is that the poster has a good sense of humour.
That said, I believe Mr.Spotter does on occasion post memes of his own creation. If they can be distinguished then give credit where it is due. If a comedian's act was telling you about funny jokes he'd heard from other comedians you'd probably say he wasn't a very good comedian.
You're making this too complicated. Rep where rep is due, even if it is simply for making one laugh.
