Myth: follow/unfollow churn drives sustainable growth

Myth: follow/unfollow churn drives sustainable growth
It inflates gross adds and tanks retention. n=190 accounts running F/U, 60-day cohort.

— Daily gross follows: +35 median
— 30-day retention of those follows: 41%
— Reach rate trend over the cycle: -2.9 points (dead-weight accumulation)

Net growth after churn-back: ~+9/day, below the +14/day of matched organic accounts. So what: the tactic optimizes a gross number that retention quietly reverses, while diluting your reach base. Net-negative once you measure 30-day retention.
