People who suck at email 

A query service that allows you to submit people who can't use their email correctly. This is tied to a plug in application that runs in outlook or gmail to flash a warning when you are sending an email to a 'sucky' person.

For example if you send someone a BCC and the forward it on to other people who were already in the CC of the original email, you can flag them as someone who sucks at email.

You can also create filters based on peoples 'suckness ratings'.
After 5 suck notifications they get an email explaining how to use email correctly And at a certain point work as an email block list after say 100 'suck' ratings they can't send email to anyone who uses the service.
