We disabled your account because your web space had been compromised your domain was hosting a phishing site. We take this very seriously and though you may not have been aware of this you are responsible for the content on your web space.
If you have been hacked we suggest resetting all password, going through your scripts and removing any that do not seem familiar. If you are running any open source software (includes forum software e.g. phpbb, Content management Systems) then we suggest you upgrade them to the latest version as this should then have security updates and patches that the old one doesn't have.
