Re: [tor-talk] Who is 93.114.40.75? Tor check page lists it and says I'm not using Tor. Another user reported this, too.

There needs to be some solution to this problem other than just telling 
people about it. This exit node is pretty fast and gets chosen by my 
Tor clients about once every 10 times as the initial exit node. I get 
to see that scary warning pretty regularly.  (It also makes me wonder
how random circuit selection is, but maybe that's just my bias because 
it stands out).

One solution would be to patch Tor so exit nodes can declare if they 
use mult-homing. The other would be to just patch Check.TPO and add
that information there.
