Re: Tool Release - Tor Blocker

["John Sprocket" <sargoniv () gmail com>]

sure, there's a lot of legitimate tor users out there. but tor is a free
community supported proxy chain. an attacker can use this great tool
in their attacks in order to keep themselves hidden. a security
minded administrator would probably not want a user to visit their site
and remain hidden. why if i being interested in protecting my website
would i want to allow a valid or invalid user to visit my website?
do we want a proxy chain for an attacker even tho it has valid reasons
for usage?

there's probably a much better way to accomplish what jason areff
is wanting to do. but this is a start. and i see where he's coming from.
and sure, his code my suck...but hey. he's an administrator, not a coder.
;-)

jason, rather than blacklisting like that, there might be a better way. you
might have to look at how tor works though.
