This is what my followers list currently looks like.
I wanted to look to see who was following me, so that I could follow back, and now I have to wade through all this crap coming from public relays. 
This has led to npub follow lists full of spammy npubs. Anytime someone generates an npub, the npubs currently trending (or whatever metric they're using) get a new npub.
Effect is the same as follow bots.

Woah crazy. I donāt even bother looking at my follower list, I figure itās mostly just bots anyways.
Probably is. I'm thinking follow count only says anything concrete, if you only look at private/paid relays.
That's my current workaround, at any rate.
Figuring out a reliable way to actually check that stat would help nostr, i know devs made a bunch of follow bots back in the day and boosted peopleās numbers for the lols to demonstrate its brokenness
I guess the idea is that they could be lurkers, but lurkers usually change the profile info a bit, if they do more than look around one time. These are all identical, so single-use npubs.
Yeah, that's fucking annoying.
