Is this an attack?

Hi! So I've been recieving like 4/5 follows every day from AI accs and most of them seem to sell OF or something like that.

I don't have that many followers (500~) and only got a couple of viral videos. I don't show my face and I only post covers and things related to my fav show (which it's not very popular). I don't watch weird content either, I only watch edits about the show so.

I don't want to lose my acc if tiktok thinks I'm using bots. What should I do? Has this happened to anyone?
