Welcome to Nostr!! Search around for hashtags (many times you’ll find whatever you’re looking for with “str” appended to the end ex: #artstr ) and see what other relays folks are using.
There’s no Big Company here to feed you information or demand ID from you. If you have a question, just add
#asknostr
at the end of your post and you’ll get answers very quickly!
If someone posts something that you don’t like, just Mute them.
Enjoy your time!!
