The "Tor Exit Node scanner" has been down for a while due to the long unconvenient upgrade made. It is however re-instated with a small bonus: From now on, the ExitNode-scanner will be self-sanitized and hosts discovered as exit nodes will automatically get removed as soon as the official ExitNode-list (https://check.torproject.org/exit-addresses) is updated.
Our removal tools that works agains DNSBL v5.0 is finally released. It's up and it has been tested both with ipv4 and ipv6-connections, so now we're ready to release it in public too. http(s)://dnsbl.tornevall.org/removal/ And if you still need manual support, you may want to take a look at http://docs.tornevall.net/x/OIBu as usual.
