I don't think it will be an issue if you don't use the global feed.

Nostr is a different paradigm in social media.

To achieve a similar result in Twatter I created multiple lists to try & get all the tweits from the people i wanted to hear from.

This is the default on Nostr but migrating is like going from a pub straight into a library. There's no need to yell anymore, we can all hear you just fine.

As new users come across, you can see the way they slowly shift their behaviours. It's so easy to avoid people on here that it compels people to adjust their behaviour quickly.
