I won't comment on the possible legal ramifications of this post, because they should be obvious to anyone doing 30 seconds of research. What I will comment on is how completely futile your efforts are. You're sending multiple requests, all they have to do is block every ip with more than 2 form submissions and your efforts become a miniscule DOS attack (which is illegal in your country, oops guess I saved you 30 seconds).
Do it from dial up and they will never be able to track you down either.
Welcome to the Internet my friend. First lesson - you are not anonymous. All that has to be done is contact your ISP with the violation and your identity becomes known to them, and law enforcement agencies.
Way to be a script kiddie.
P.S. I don't understand all the posts in this thread. Am I missing something, or has Perlmonks really slid this far down?
