I have added disabled account options. For those companies that fail to reply to removal requests or make bad reports, their accounts can/will be disabled.
I am nearing the release of the first version of a WHMCS addon. This addon will check your client's name, phone number, IP address, and email against our database and notify you of any reports. Additionally, users will have the ability to directly report a client from within their WHMCS interface. I am also working on getting the addon approved for the WHMCS Marketplace.
