Have you checked tor's logs?
They are usually in /var/log/tor/log

If you have logrotate configured, they might have already been deleted,
because 30 March is more than 1 week ago.

Have you tried reading /var/log/sys log directly?

Most of the time, blacklisting just makes Tor log a message in its logs.
And the directory authorities stop publishing the relay in the consensus.

(We haven't made any changes to required protocols recently. If we do,
very old Tor versions may shut down.)

Here's what we need to know to be more helpful:
* your relay fingerprint
* your Tor version
* tor's logs when it shuts down
