Blacklist Alert Service

A banker from downunder and a wee to the right just informed me that he can't read my blog because WebSense, used by his bank, is blocking the Docuverse domain.  I know where to go for regular checkup of my credit ratings.   Where can I go to find out whether I am on blacklists and how can I get myself off them?  Is there a notification service and correction procedures for blacklists?  If not, I think there is a need for such a service so I'll help in putting one together.
