I answered a question you asked.
It's a done deal, it hit the FP, got 262 UV's, people liked it, it's drifting away so too late, what does it matter to you?
I've done it myself. Done it the other day on Natalie_vance's UK wedding meme. Only thing was, I posted that I borrowed it, but that's just me. The FP gets tons of reposts.
Your meme was a success, don't penalize yourself.
