Was your account hacked or locked? This procedure applies only if your account was hacked not banned/locked. From taking a quick look at your account, it was most probably banned for spamming and low quality posting.
Banned and locked are two different things. Actually, signing a message is needed for your account to be unlocked. The message shouldn't be that way since it wasn't hacked or lost but rather locked. If it really is banned then that's another issue.
As for OP, just wait for a global mod like hilariousandco to investigate whether it's banned or locked (which they also have the power to unlock it for you).
