The project comprises a set of tools to review information on internet organizations, and an actual database which already counts about 200 blocked organizations and about 27 million blocked IPs. For more information on the tools and the criteria used in compiling the ban list, please read the project README.
The ban list is work in progress, so use at your own risk. It is wired to pisto’s servers: ZOMBIE OUTBREAK! (pisto.horse 6666) and pisto.horse 1024. piernov added support for suckerserv, but it is not yet tested, and there are most likely performance problems due to the size of the list.
If you want to contribute, you can drop an email to pisto or send a pull request on the GitHub repo. Feedback on the current ban list and reports of proxies/VPNs are especially welcome.
