Runefox writes "ZDNet UK has a story about a new SPAM defense mechanism called BlackFrog, a response to the demise of Blue Security's BlueFrog. According to the article, the new service is based on a P2P network of clients, called the 'Frognet', which allows the opt-out service to continue functioning even after a server has gone down, making a DDoS attack like that which crippled BlueFrog ineffective against the new service."
