Just a suggestion: This act that guy made may have violated some laws one way or the other.
spam is still a spam no matter what form it may be. Try contacting law enforcement agencies about it. You ca help save others from crashing their systems and out an end to this spamming spree. FBI has a handfull of agents wiilling to help about it... or u can make a copy of the URL and tell mankind not to enter that site and its affiliates. All it takes is will.

Of course, thats just my opinion and its a suggestion. Its up to you

regards and the best of luck!!!!!
