something strange happens to my user

I use followliker and i have user with 42300 followes
Yesterday i got 200 new followes from comments = 42500
and today i look its back to 42300 And I blocked from commenting to 38 hours.
Where is the 200?? What's Going On?? It happened to someone?
Instagram know I'm using bot?

And another thing I can not search users and followers count has been stuck for a few days.

Not good. Other users are reporting similar activity on their accounts. Did you verify these 200 followers were actually showing on the Instagram app? Or are you saying this solely based on what FL statistics are telling you?
