Is the F/U method dead?

I’ve been using the follow/unfollow method on Instagram to grow accounts, but I’ve noticed that Instagram has recently reduced some of its limits. I’m curious to know if others have experienced changes in the effectiveness of the follow/unfollow strategy post these updates.

Has anyone noticed a significant impact on their engagement or follower growth? Are there any adjustments or alternative strategies that have proven effective in light of these recent changes?

As far as I remember, the limits keep getting decreased constantly. I remember 5 or 6 yrs ago you could follow/unfollow hundreds of people with no issues lol.
