What can or should be done about these failures to post to relays? I assume I wrote something that broke a rule, but I have no way to find out.

I tried to find some kind of list of policies or rules or something for each relay but wasn't able to find anything useful. Unless I missed it, they don't have actual websites with stuff like that listed. Just wondering if anyone has advice. How would you find out what policy you violated or why you were blocked? Is it even worth worrying about, or should you just add more relays to your publish list and move on? #asknostr
