Why doesn't instagram auto-registration work?

Question

Python

# https://www.instagram.com/ajax/bz:[{"page_id":"v1xv8g","app_id":"936619743392459","device_id":"XVf46wALAAF1Y1_787Xit0_a36gB","posts":,"trigger":"qex:expose","send_method":"ajax"}]

The code above :)
The beauty is that when I start comparing headers and other things when registering an account with a browser and my script, there is no difference <except that the browser makes some other requests, possibly related to the authorization process>
Is it possible that instagram could ban all proxies and there is no way around it?
Or did I still make a mistake somewhere and between my requests there is something in common that helps Instagram to ban my proxies?
Don't try it on your machine <pancake ban> {maybe 1 time} - it will unban you later, but if more than 2-3 times ban forever :(

Answer 1

Requests + Instagram. People from real browsers hardly register. There are also cookies that depend on javascripts.
