Hi Colin, > They are using tor services to generate their multiple ips.

They might be. If you email the exit node operators[0] and let them know you're receiving abusive traffic via the web (port 80/443), and include the IP address(es) of your forum, they may be able to restrict their exit policy to block traffic to your server. That said, there are currently over a thousand exit nodes, most of which allow web traffic, so this may not be the most efficient solution. > However, our current problem individual is using your services to > perpetrate the very oppressive, abusive behaviour that your system is > designed to help fight. Please let me know if there is anything you > can do. Another option is the Tor DNS blocklist[1]. If you have a dedicated server or VPS you can configure it to reject traffic from Tor exits (e.g., for Apache[2]). If you don't have a dedicated server or VPS, you might be able to set this up in the forum software itself (e.g., for phpBB[3]). I hope the above is helpful. Once the troll gets bored and goes away, I hope you'll consider opening up your forum to well-behaved Tor users. Regards, Sharif [0] Most exits have this information on a webpage served from the exit node IP, e.g., http://92.222.113.177/; you can also often find this information via atlas, e.g., https://atlas.torproject.org/#search/92.222.113.177.
