Project Cerberus

Project Cerberus is a webservice that enables your ExpressionEngine sites to report member spam and then check member actions against a master database of known or suspected spammers.

This is a realtime network. If you send an update to Cerberus then that data immediately becomes available to everyone else who has any of the Cerberus components installed and active.
