A few thoughts

1. Spammy accounts can be (and more often than not are) humans, they are not necessarily "bots", i.e. run by software

2. When people find bots useful, we call them "AI agents" :)

3. Twitter used to regularly purge followers like this from their UI; Instagram still does this today. Meta estimates that 10%+ of their users are bots, read it in their 10-K

4. There are likely mistakes in both the spammy user classification and users that are actually spammy but have yet to be classified.

5. I don't think anyone is/was fooled that follower accounts on any public social network—web2 or web3—are all real people. So better to adjust to what we think is the best known proxy for realistic and keep making progress on other stuff.

As for me, some of the accounts (40-50%) are really humans.
