Intagram follower leacher

Hey everyone. I'm a developer and recently build an Instagram app without using of the provided api.

Exactly tomorrow night of the release, the web configuration of instagram changed.
Now I can't leach user followers.
Any ideas about, how to make something remains at working longer are welcome. Crawler is my final approach, and c# is my favorite language.

Sorry it is a common problem. Not using the api leeds to 2 different solutions:
1. could work a while: headless browser automation. Will work for small accounts (because of pagination) and last a while.
2. Emulate graphql request. Worked pretty solid the last time I used for accounts with 500k+ followers.
In both solutions you need to be logged in with a user. Make sure it is not your own. To aggressive requests will give you a time out.

Best luck.
