Hi guys,

One of my tor server seems to be getting a lot of abuse reports from the ISP from stopforumspam.com http://stopforumspam.com/.

http://www.stopforumspam.com/ipcheck/212.47.246.21 http://www.stopforumspam.com/ipcheck/212.47.246.21

Any idea how to reduce those to a minimum in a reasonable way?

Ideally, the forums would work out some way to block connections based on behaviour, rather than source IP. But in the absence of such sensible measures, there are some things you can do.

Can you block particular IP ranges / ports in your exit policy to avoid the complaints?

For example, if the complaint is from a destination 1.2.3.4:80, add a rule at the *top* of your exit policy saying: ExitPolicy reject 1.2.3.4:80

You can add IPv6 addresses, port ranges and address masks too: ExitPolicy reject 1.2.3.4/24:443-445 ExitPolicy reject [2002::abcd]:8080
