Key facts

Meta removed 3.7 million accounts and pages, impacting follower counts [1].
Instagram had several outages, disrupting user engagement and follower activity [2].
A new feature lets users add tagged posts to their profile grid for more visibility [4].
Algorithm changes affected follower growth for small creators [3].

Meta removes 3.7 million accounts and pages

Meta, Instagram's parent company, took action on 3.7 million accounts, pages, and pieces of content in partnership with the Singapore Police Force [1]. This removal targeted organized criminal networks that used fake accounts to promote scams and fraudulent offers.

Such a large-scale removal can lead to noticeable drops in follower counts, especially if a portion of an account's audience was made up of fake or compromised profiles.

For most ordinary accounts, this means a possible dip in followers, but it also improves authenticity and credibility.

Widespread Instagram outages disrupt engagement

Instagram experienced several widespread outages in September 2026, affecting millions of users and disrupting access to the platform [2]. These outages also impacted Facebook, Messenger, and Threads.

While the outages were temporary, they interrupted user activity, limited engagement, and may have slowed follower growth for many accounts.

If you saw a drop in engagement or follower activity on specific days, the outages were likely the cause.

Instagram introduces tagged posts feature for profile grids

Instagram rolled out a new feature allowing users to add posts they are tagged in directly to their profile grid [4]. Previously, tagged posts appeared only in a separate tab.

This change lets users showcase collaborations and tagged content more prominently, potentially increasing profile visibility and attracting new followers.

Accounts that collaborate with others or are frequently tagged can benefit from this added exposure.

Algorithm changes affect follower growth for small creators

Instagram made algorithm changes in September 2026 that impacted how content from small creators and larger influencers is shown [3].

These changes may have altered follower growth dynamics, with some creators seeing shifts in reach and engagement.

If you noticed changes in your follower trends, algorithm adjustments may be one reason.
