Re: How to ban many IPs?

["Matt LaPlante" <cyberdog3k@xxxxxxxxx>]

Personally, I run my tor node as transport only (non-exit).  I can't
risk opening myself up to illegal activities by running an exit node,
but I figure the least I can do is provide decent transport as the
middle-man, and let the people running exit nodes concern themselves
with the legality of the activity.
