You’ve got some old relays in your list, you need a refresh for sure. Encourage you to signup for the #AUStriches relay at https://relay.nostr.com.au - that will get you seen in a different time zone for example.

If you’re seeing the same ppl in your replies all the time I’d encourage you to 1) try some diversified content and 2) go follow some other plebs and engage them on topics that interest you to spread your wings a bit
