Hello friend; I am completely sympathetic to you. But I do not think that the Administrators will be able to unlock your account. Because virus and other malware links have been posted from your account.
I may agree with you that your account was hacked. But the question is how will you convince the forum admins And if they unban your account may be other members who got banned for the same reason will be applying to unban them too. They will also be claiming to be innocent.
I think if you can provide some proof of hacking; may be Admins consider your case sympathetically. Still chances are low because every sinner(though it may not be you) always claims to be innocent; it is universal truth.
