It's important to make sure that you have a relay that filters out the spam and then Global is nice. I hard-coded my Nostrudel fork to my relay running strfry with a lot of filtering so it's a nice experience for the user

it's a good first step, but my dream is to combine client side filtering into a based fork of noStrudel
That would solve the message not found nonsense that gets annoying but you have to keep relays clean and safe from abuse too.
