This site is a tool for Instagram that allows you to quickly determine followers who have not been engaged with you in recent times and then, in bulk, have them unfollow you.

IG is about people, not numbers.
Armed with this information it will identify all the users that you have no interation with in the last 60-180 days and allow you to bulk delete them
1. You have to trigger the site to collect stats. You do this by hitting the "Request Rebuild".
2. Wait for the refresh to complete. The refresh process happens offline and can take some time to complete. Currently there is only a single refresher running, so if there is a queue of users waiting to refresh you need to wait until that is finished. Once your refresh starts, it can take around 15-30 minutes to complete. You can check the status of the refresh by hitting the "Refresh page" button. The Request Status is shown in the top near your image
3. Once the data refresh is complete you will be able to see the list of potential users that will be deleted.
4. Select the number of days back to go (60/90/120/180) and you will be shown all the thumbnails and names of the users to be culled, as well as the last time they interacted
5. If satisfied, click the request cull. Once the cull process starts it will take around 2-3 seconds per follower to process, so if you have a large number of followers it may take some time to complete.
To confirm - if you are following someone, they will not be unfollowed.
Clicking on the user a second time will remove the green background and un-protect them.
The system has no way to know when a user started following you. All it can tell is check your photos for likes and comments. If a user has only recently started following you, but has not yet given you any likes or commments, then that user is considered to have not had any interaction with you in the last 180 days.
This system collects data when a rebuild is run. The follower/following count is as at the last time a rebuild was run and you may have gained or lost followers in that time.
There appears to be an issue with Instagram when someone deletes their account. If a user that is following or followed by you has their account completely deleted, the follower/following count you see in Instagram is not update. This application requests all the users and totals the number returned rather than relying on a single user count number and thus I believe is more accurate.
I have recently added a selction of "Cull Type" to the page. If you select normal then inactive users as listed in the inactive follower lists are removed as normal when the cull is run. However, if you select Timid as the cull style, then before a user is culled some additional information is taken from the user profile and used to determine if the user is likely to be a spam account rather than just a normal user who has become inactive. Only those users considered likely to be a spam user are removed. Unfortunately it can't calculate this information in advance, so I can't deteremine how many followers specifically will be removed by this process.
Recently, unfortunately, the profile of bot/spam users has changed and is more difficult to pin down with any more accuracy. This means that the timid cull style is no longer very effective. Often if you select timid cull style you'll only manage to remove a handful of users. I no longer recommend the use of this option
