well if u looked at the trade u would have seen there is no expiration date etc...but yr mistake was assuming that there was one.
technically its not cheating or anything because it was within the rules and the trade was never withdrawn. You shouldn't have counted on it expiring on its own when u didnt know if cbs was setup that way. 0evg0 has made trades and then withdrawn them and hes a total ffb newb. So u should have withdrawn or double checked.
But from B
it seems justin clearly knew that u thought the trade was dead and had no intention of offering Moss given u were giving him [censored] about not accepting the trade.
so thats kind of messed up in terms of sportmanship but technically its not against the rules and there is nothing the commiss can do. its between u two guys
