Blue Security calls it quits

From here

A startup whose aggressive antispam measures drew a blistering counterattack from spammers two weeks ago that brought down the company's servers along with a wide swath of the internet is shuttering its program targeting junk e-mailers.

In an interview with Wired News, Blue Security CEO Eran Reshef said the Israel-based company was closing its service Wednesday. He did not want to be responsible for an ever-escalating war that could bring down internet service providers and websites around the world and subject its users to denial-of-service attacks from a well-organized group controlling a massive army of computer drones."
