This pretty much comes down to a double scam honestly. The OP tried sending 1 kind of token and pass it off as another, while the receiver just took the token and disappeared. (Corrected by Darkstar_)

They both deserve a tag IMO and will receive 1 from me. Even if the situation is resolved I do not believe the tag on the OP should be removed as he is trying to deceive users when trading. Dishonest trading should be tagged period. (OP tag removed)

On a side note, If users would be smart and use escrow, we wouldn't be reading this thread. Although it cannot be enforced, escrow should be a must. Why risk 100s of dollars possibly when you can pay a .5%-3% fee and trade safely?
