Hello,
You've been suspended for having a proxy on your account. That's against the Terms of Service to which you agreed upon signup, and is dealt with under our zero tolerance policy. As per section 8 of the Terms of Service you can have no further access to the account, its files, or databases for any reason.
If you believe this is an error, I can ask someone to look into it....but don't waste our time if you're planning on lying.
