Instagram Help Center

If your Instagram account switches between public and private too many times, temporary limits may be placed on your account including:

• Limits to the number of follow requests you can approve per day.
• Removal of existing follow requests if you try to change your account from private to public again.

Accounts that repeatedly switch between public and private can create poor sharing experiences for others. This behavior is discouraged on Instagram to help protect the community from inauthentic activity.
