Yes, leave it as soon as possible. Check this: https://bitcointalk.org/index.php?topic=5118992

Now is a best time to leave, if your account is not locked,  and while Tradesatoshi has changed their withdrawal fees after this post (https://bitcointalk.org/index.php?topic=5118992.msg50245384#msg50245384) at BitcoinTalk.
