Anyone actually gaining more followers on instagram successfully?

Slowly, yes. What made the difference for us was picking one narrow topic and posting Reels on it consistently, a few times a week, for months. Random posts on whatever got almost nothing. Collab posts with accounts in the same niche helped too since you show up to their followers, and replying to every comment early on keeps people coming back. Anything promising fast followers is usually bots, and those wreck your reach.
