When I recently inquired about the dozens of follow-ups I receive daily from suspicious people,

The answer was, "Don't worry, they are all users." However, most of the dozens of users who follow me every day, even now, have not created a single image or video! Is that normal?
Moreover, I don't see any "Like" for the images and videos I created, and I don't think they viewed them and followed me, but is it still safe? It's really hard for me to block them every single day.
