So new, not familiar with what you mean by filter in this instance on here.

Are you using Damus? I think other clients allow you to filter global too.
Basically, you add some relays like nostr.land and nostr.wine, and you can filter the global feed by only viewing notes submitted to those paid relays.
However, in order for me to see your notes in global, you would have to pay for the relays.
If I follow you (I am) then I will see your notes regardless, because your regular feed pulls from all the relays you’re connected to.
You probably need to add some more relays though. I’m only seeing 4 on your profile. You can visit my profile and just copy my relays.
