This limit is so Instagram doesn’t flag your account for suspicious behavior.

Filter settings

If you want, you can unfollow only those who don’t follow you,

You can also create white and black lists to tell Fast Unfollow exactly who you want to unfollow and don’t want to unfollow.

Maintenance and Support


After setting up your targeting options, simply hit “Start Growth”. AiGrow will start to run and continue until you tell it to stop, never overstepping the limits imposed by Instagram.

If for whatever reason something forces your growth to stop, we will automatically let you know through email and provide possible solutions, as shown in the example below:

Fast Unfollow

Fast Unfollow charges on a quantity-basis. 

This means that the more unfollows you want to perform, the more you pay.

The prices are as follows:

The main advantage of Fast Unfollow’s service is that its website is really simple to use. The unfollowing speed is acceptable but there is no free trial for new users. So, to even try their service you have to buy one of their packages.

On the other hand, AiGrow is a complete platform with lots of features for growing your Instagram account while simultaneously unfollowing whoever you want to unfollow. It also gives you a 5-day free trial with no limit to the numer of people you can unfollow.
