It's likely most followers are dead accounts and bots anyway. Anyone who is a default follow in primal also has inflated numbers. Once you remove the bots and dead accounts, the numbers look more realistic for the theoretical number of users on Nostr.

nostr:nprofile1qqs0dqlgwq6l0t20gnstnr8mm9fhu9j9t2fv6wxwl3xtx8dh24l4auspzemhxue69uhkzat5dqhxummnw3erztnrdakj7qg4waehxw309a4x2mrv09nxjumg9ekxzmny9uq3vamnwvaz7tmdd3jkkafwwfjkzmre9ekx7mp0yahvqr has been doing great work to make actually usable stats at npub.world, removing bots and accounts that never interact.

For instance, I show around 5k follows on nostr.band, and around 3.6k on npub.world. Ava is about 33k/6.6k. Yours is very close at 1.8k/1.5k.

These numbers only matter to inflooooencers anyways. Bragging about your follower count is degenerate behavior, best to ignore those kinds of people.
