Someone botted me with 23K+ followers over the past couple days. 

It does not seem like there is currently anyway to deal with them. 

Went from 10K -> 43K followers

Maybe you were added to the autofollow list, I would if I was the maintainer :) 
cc @proxystudio.eth

zach is on the list and has 25,000 autofollows, but bots are a separate issue

noticed a bunch of low quality accounts like this

Guess then if you're on autofollow it's just the new sign-ups which are of low quality. Not specifically targeting you but doesn't promise any good for the platform :(
