LoL...what a fkn clown!
(apologies, but speaking as someone who knows for sure that the account MatTheCat was compromised, I can come to no other conclusion about you)
Nobody here is able to definitely say you were or were not hacked. Fact is, scams were pulled on your account, so unless you are willing to compensate the losses you shouldn't get it back. You already admitted that you ignored unexpected btctalk private message emails which would have helped to stop it. It's always convenient when the account owners don't log in for the short period of time the scam took place.
