Hi! I just tried it but get the following error message:
VM48:12 Uncaught TypeError: Cannot read property 'querySelector' of undefined
at goToSubscribers (:12:67)
at :83:1

@Schludi Since the last implementation was totally dependent on the classname of the tags present in the instagram site it got outdated when Instagram updated their site. I have updated the script to work irrespective of the tags now.

It's working now but the usernames are redacted as they are from my list.

P.S. Sorry for the late reply. I don't remember getting notification for your comment on my gist. It must be due to my habit of doing "Mark all as read".

All the
document.querySelector('[aria-label="Close"]').click();
should be changed to
document.querySelector('[aria-label="Close"]').parentElement.parentElement.click();

Not working, just tested it.

hey how should i use this

How to use it (27-04-2023, still worked):

1. Login to your instagram account (via web), go to Profile tab
2. Click the Followers text, then open Console tab of your any web browser (google it if you do not understand this dev-tools)
3. Copy the code to the Console textarea and hit enter; Or run the .js file by download the javascript code, save the file (.js ext.) and open with your web browser that open the instagram Profile tab menu
4. Wait for the result, let the code's running until finish.
5. Run one of the functions provided on the .js code, for example: type getResults() or getInstagramStats(10) in your Console textarea, then hit enter to get the result
6. Good luck! The latest code you would run on is the latest, the most bottom one in this comment section (look at the comment timestamp)

great work, works like charm!
one tip: you may add some random wait time in between scrolls, just to make it a lot more like human interaction.

Line 30 and 40 breaks if you have more than 1k followers

https://gist.github.com/Acesmndr/eb9fdc42b8fed0416ee658af692adb69#file-instagramunfollowers-js-L30
https://gist.github.com/Acesmndr/eb9fdc42b8fed0416ee658af692adb69#file-instagramunfollowers-js-L40

Ex: for line 40
it should be parseInt(document.querySelector('a[href*="/followers/"]').firstElementChild.textContent.replace(',', ''))

Add .replace(',', '') in line 30 the same way.
