It’s probably one or two of your relays that are showing you fediverse results. You might have to try turning some of them off to see if that helps. I think the nostr.band relay shows a lot of content from there. I also set up mostly paid relays that I read from so I can curate my feed better.

I see, I'll try that for sure. I do see these posts seem to be from mostr.pub and momostr.pink mostly, e.g. nostr:nprofile1qqsfuncrv0czqknam92svndtgwrwuh7u2znwhgn73ze0lspyar44kkspr9mhxue69uhhyetvv9ujumt0d4hhxarj9ecxjmnt9utxes9t
Perhaps there is a way to block these domains (if that is the correct lingo)?
Removing these from your relay list should do the trick assuming they are in your relay list. I will say I do converse with people from activity pub and they do converse back so I’m not sure what the cause is of what gets blocked and what does not get blocked.
