Instagram will also limit how many people you can follow within a period of time. If you follow too many people within an hour, or even a day, you will receive a message telling you the limit has been reached. As far as I’ve been able to confirm, Instagram only allows you to follow/unfollow 160 people per hour.
What happens after 10k followers on Instagram?
Once you have 10k followers, Instagram will make it easier for you to get people to your website via Stories with the swipe up to link feature. Swipe up is the only way to get a direct link from your Instagram to your other web properties. And, it’s available in STORIES, if you have 10k followers.
