Separate fake FB followers from real, and delete them

I am looking for a freelancer who can help me separate fake followers from real followers on my Facebook account and delete the fake ones. Purpose of Facebook account: Business Current number of followers: More than 5000 Approach for deleting fake followers: Delete all Ideal skills and experience: - Strong knowledge of Facebook algorithms and fake account patterns - Experience in identifying and removing fake followers on Facebook - Ability to efficiently and effectively delete a large number of fake followers - Attention to detail to ensure that no real followers are mistakenly deleted Process to identify fake followers : some time ago we paid freelancer to add 10000 followers to our FB account(did not know there is something like fake accounts) they were added all within 1 week few years back, so if you group all followers based on date they started to follow our account, it will be more than clear which are fake. Deletion of the accounts would be ideally done in some automated way, after I will confirm (select/unselect them)...dont want to click 10000times to remove each of them manually. If there is no automated way, ok, will do that manually, but prefer some group way....the same process will be repeated on 3 separate accounts. Permissions to manage our FB account will be not granted(sorry, but security issue) so if any external tool will be connected to our account, it will be allowed only to read-only followers informations. Another option is you to install whatever tool through remote screen on my system, so I will be able to run it without external access, after I decide if all selected are really fake accounts, I will press the Unfollow button(nobody external can have acces to manage our FB page. Example : expect you to use FB Graph API or whatever tool, to extract the user ID and USER "DateStartedToFollow" and provide it to me in XLS or whatever. then I will sort it by this date, and will see that "day1-1follower, day 2 - 1200 followers, date 3-4500 followers, day 4-1folower, etc....so we will delete ALL users from DATE 2 and 3
