Guides, tips & follower insights
How to Tell If an Instagram Account Is Fake or a Bot
Fake and bot accounts tend to share a specific combination: little or no post history, a following count far higher than followers, a generic or stolen profile photo, and comments that feel copy-pasted rather than specific.
Why Did My Instagram Followers Drop Suddenly? Common Causes
Sudden follower drops are almost always caused by Meta purging fake or inactive accounts, a batch of real people unfollowing at once, or accounts getting deactivated or removed — not a mysterious shadowban reducing your follower count.
How to Track Your Instagram Follower Growth Over Time
Business and creator accounts get built-in growth charts through Instagram Insights, while personal accounts need manual counts or a third-party tracker since Instagram doesn't show historical follower data to regular profiles.
