Banning proxies

[yazoo]

Hi!

I am running a forum, i have a person who has activated app. 30 accounts, he wants to destroy our forum.
He is only using proxies, how can i block him, i know in which country he lives.

Please all info is welcome, this guy is really dangerous!

Thanks!

I forgot to add:

I validate all new members by hand, is it possible that i check the IP using a list or program to scan if it might be a proxy?

Thanks!

You can collect proxies and save them in your database. When an user visits your site, you try to find his IP from the database. If found, you can say he is using a proxy and ban his access.

To implement that, you should know how to deal with the database. Maybe you'd better find a PHP programmer to help you.
