Yeah, I was in the same situation — skeptical but curious. I ended up reading a thread on https://onlinecourses.csicy.com/forums/topic/boost-instagram-account/ where users shared their go-to platforms for checking follow data. There was one method mentioned that only required a username, no password or login, which made it feel a lot safer. It worked for public profiles and laid out recent follows in a straightforward timeline format. Not perfect, but reliable enough without crossing any lines.
