[tor-relays] Is the public information for relays trustable?

If asking if what you see on metrics about MX or
any other country is correct, yes it generally is.
Though if you discover errors, you can file a metrics
ticket with the suspected data in error and technical data
proof that shows suggests metrics is wrong.

"Hearing that some ISPs block, thus no exits
should be possible" is not technical IP data
that anyone can look into.

Most big cities in non control freak countries
will have some ISP that is more open to trying.
You may have to talk to them about special
hosting options you could make together.
