Someone gave me 12k in EC last night....

[Soandso]

I was semi afk in the tunnel last night when I saw a trade box pop up with 12kpp in it with the accept button. I was a bit confused but I hit trade and got the 12kpp as you don't gotta tell a black man twice to accept free money. Now however I feel kind of bad as I'm guessing this was either prolly a mistake and the person meant to give the pp to someone else or it was someone spreading around RMT pp to try to get people banned? Should I accept this free money, try to find the person who gave it to me, or simply destroy it for fear of accepting RMT funds.
