I've been getting follows by new accounts who follow thousands, and have followers of 0, or in the single digits. No posts. I block them.

Mostly their main account is on a different instance so I check there. Sometimes they have posts and/or followers on it.

Agreed. I installed FediFollow on my desktop which allows me to see most instances without having to sign in to it.
