Comment:

 This bug has a serious non-obvious impact that
 potentially affects all Tor exit operators.

 Due to exit-list inaccuracies, the popular SecToor list
 operates a /24 DNSBL that some service providers use
 for blocking access:

 http://www.sectoor.de/tor.php#en-listed-net

 This /24 list can cause operators difficulty
 with their ISPs due to collateral damage to
 other customers in the same address block
 as their exit operates.

 While it is obvious that service providers
 should not use this list at all, it's also
 obvious that not everyone engages common-sense
 in such matters.

 Removing the problem should make it possible
 to convince SecToor to decommission the
 netblock DNDBL.
