Edit - Primal’s default ordering of the home feed is: 
Trending 24hr
Most Zapped 4h
Nostr Hightlights

The last 2 are the feeds of people you follow. The other ones are aggregate feeds. 

I understand this is a discovery mechanism for people new to Nostr however it has unintended consequences we should examine.  

 I stopped using that client after the shadow ban incident. Trust, once lost, cannot be recovered. 

 What shadow ban incident? My feed on Primal feels, scant. I'm worried shadow bans are occurring.
