 https://arthuredelstein.net/exits/
 lists a pile of exit relays, including some very fast exit relays, that
 are failing all of their dns queries. That is, they claim to be exits but
 Tor clients probably rarely use them, yet clients still *try* to use them,
 contributing to the long tail of low-probability high-impact misery of
 being a Tor client.

 We should verify that we agree with his scripts, and also make sure we are
 comfortable running the checks on our own.

 Then we should contact the affected relays, and either get them to fix
 their dns, or figure out what the bug is, or failing all of that, set the
 badexit flag for them to save clients the trouble of trying them and
 failing.

 Then once we've done a round of that, we should come up with a process by
 which we repeat it regularly.
