i'm building the feed viewer still... as i was implementing the refresh function there was posts sticking to the top because they were sorted by timestamp in the future, like 5 minutes or so, and some of thenpubs that posted them did it several times in a short space of time.
these are the relays it was configured to read from:
'wss://relay.nostr.band',
'wss://nos.lol',
'wss://relay.nostr.net',
'wss://relay.damus.io',
'wss://relay.minibits.cash',
