We have been using e-mail filtering for some time, but no matter how many services are out there protecting the InBox, Rolex watch offers and Girls Gone Wild in Nepal still gets through. Make the spammers pay more for bandwidth, why not?
How about an IIS tool that recognized unauthorized behavior/poking around and redirected the hacker to a honey pot server/infinite loop death trap?
Excellent.
