Don't allow circuits with same countries
Is there a reason Tor browser allows countries to have nodes from the same country more than once within the same circuit?
As far as I know, middle+exit with same country nodes is common. I have hardly/never seen all 3 countries with the same country so I assume protection for this has already been implemented? Is the same done to make sure entry+exit nodes do not come from the same country?
Why not add that functionality for middle+exit nodes?
