Tor relays are public and easily blocked by IP. To connect to Tor
network users where Tor is censored have to use bridges and even PTs.
But, what happens on the exit? Many websites block Tor IPs so using it
to access "clearweb" is not possible. Should we allow and start using
"exit bridges"? In I2P we have not this problem since there is no
central IP list of relays.
