The anti-spam group Blue Security whos tool Blue Frog I use has been under severe attack from the largest spammer (PharmaMaster) in the world. This tells me 1 thing - its working. These spammers wouldnt waste the time, effort or bandwidth if Blue Frog wasnt hurting their businesses. After receivng serevals threats myself I thought about stopping Blue Frog. But then they would have won. So I shall continue and would recommend the tool to even more people - this stuff works!

Aside from blackmail emails sent to community members, there were two separate attacks on Blue Security itself. The first attack was to block worldwide access to Blue Security's corporate website by tampering with the Internet backbone using a technique called "Blackhole Filtering". The Second attack was a DDoS attack on Blue Security's operational system.
