Hello,

What are some of the most common reasons for relays and exits to be banned from Tor?
Had it happen to all of my 5 nodes and I'm currently awaiting response from bad-relays list.

They all present this in logs
Jan 18 20:41:40 example.com Tor[2439671]: http status 400 ("Fingerprint and/or ed25519 identity is marked rejected -- if you think this is a mistake please set a valid email address in ContactInfo and send an email to bad-relays@lists.torproject.org mentioning your fingerprint(s)?") response from dirserver 204.13.164.118:80. Please correct.

All of them have been running just fine before

I'm genuinely curious if others also had it happen to them, and the reason behind it.

Thank you.
