Follow/Unfollow still safe?

Short backstory: Made an account in the fitness quote niece 8 monthsa ago. Got shadowbanned for doing too much follow/unfollow and likes/comments MANUALLY (500 follows a day + several hundred likes). Got unbanned a few days ago (apparently switching to a private acc for a few weeks helped).

Now, progress is really slow because i completely stopped doing Follow/Unfollow. I wanna start doing F/U again.

What is a very very safe number of follows per day to do so i dont get shadowbanned again?
Is F/U even worth it anymore? My acc has 3k likes so i am still very small

I'd say it's worth the effort to f/u if you are producing great content and keep at it. These are real people that will be looking at your new posts. If they find it boring, they will leave you. Do more likes and comments. Interaction is key to keeping your followers.

I 'm Unfollow 50 per hour
