I removed the guy who rejected me from my Instagram follower list but why would he follow me back again a week later?

I’ve just created an Instagram account posting my piano covers just for fun. Although after he rejected me, he followed my newly created account and even got his other two male colleagues to follow my account even when I didn’t ask him to. Not sure why he asked his male friends to follow my account. Probably to support me or maybe perhaps i have very low followers for my newly created account.

We no longer contact each other. I felt that i don’t want him to see my updates so i removed him and his 2 male colleagues from my follower list, but then a week later, he followed back my account. Not sure why he did so….

Since I followed his account as well, at times it hurts me seeing his updates and Insta stories hence I decided to unfollow him and remove him from my follower list again up till now… I even unfriended him on Facebook. I’m just not sure whether its the right thing to do. Also just wonder what he feels about it….
