Re: [tor-talk] How important is it that the MyFamily option be set correctly?

[Pascal <Pascal666@xxxxxxxxxxxxxxxxxxxxx>]

Removing relays in the same /16 leaves me with 120.  Matching contact 
strings based solely on alphanumeric characters adds 4.  Adding a 
unidirectional association check brings me up to 142.  Adding a search 
for similarly named relays (such as Pascal0 and Pascal1) brings the 
total to 171.  Keep in mind there are probably some listed in here that 
are not really related.

I have posted the script and its output at http://173.213.78.125/tor
