There is also a min_wot filter you can use if you go to advanced mode, but it requires reading the spec. Also, a way to hack the feed is to add a kinds filter for kind 0, which will show profiles instead of notes, although it will sort results by most recent profile edit.

Thanks, tried it here:
Is there anything I can add to it to exclude my follows?
Does `scope: network` not do the trick?
It sort of works (maybe the best I can do for now) but doesn’t exclude people I already follow.
I wanted it to replicate the feature on other social apps that suggest users to follow within your network/social graph.
Feels like we’re missing suggested users on a lot of apps that might improve discoverability. The global ‘trending’ use and post feeds of apps like Primal could be offputting to non-bitcoiners. I’d expect new users to communities like siamstr, artstr, etc. would like to find other people in that community rather than Bitcoin/Nostr maxis. 
Totally, and I really like the feed you've made, because it sort of actually does that! I'm not able to reproduce the problem of existing follows getting in there though. I even double checked the code, and "network" doesn't include your follows. Maybe send a screenshot?
Ah, think this may be a bug with Coracle and Nostore 🤔 It’s not loading my follows on my profile either.
Follows load and custom feed works fine when logged in with npub or extension on desktop browser extension.
