relay.nostr.band only returns ~9k…
relay.nostr.band only returns ~9k of them bcs the rest have zero trust rank and are not returned by this relay. Looking at a random sample of your followers, I'd say those are indeed bots. To get the rest from my relay, try wss://relay.nostr.band/all
With other relays, most of your followers can be downloaded from nos.lol, nostr.mom, nostr.oxtr.dev and offchain.pub. Most relays have limits on number of events they return, so you'd have to scan using since/until to get all events.
Many of these relays are overloaded. It took several minutes for nos.lol to send me 300 contact lists, and then it closed the connection. Similar with nostr.mom, didn't terminate, but took 337 sec to send me 500 events.
I uploaded the list of your followers here
