ok, then we gotta find out who would do this, and contact them asking why their doing it, (if it's not just out of spite), this will probably cause them to stop what their doing. We could follow madpenguin .org's example, here is what they placed on their main page after being dos attacked...., it appears they took it down, but it was along the lines of: Could whoever is attacking us please come forward, if you don't we will be forced to retaliate, but if you do and explain your reasons we will wipe the slate clean and resolve the problem. Thankyou for not being a coward.
It was really effective, the attacks ceased, and I presume they contacted the attacker and resolved the issue.
