Are you not reading the OP before commenting? He said that he tried on his home wifi netowrk. How can that be bad? Just cause you are selling proxies doesnt mean you should comment on random threads suggesting them better proxies.
I don't log into Instagram every time, I open the browser once with a chrome user profile that is already logged into to Instagram. Then I do everything in one session, just hitting different URLs. IS this what you were asking?Are you using the session ID to log in? I'm running my own web-based scraper and it works just great on large amounts of data.
UPDATE: I managed to successfully run the script for 3 hours today and followed 65 people while liking roughly 40 posts. I did it from my home wifi network. Not sure why it worked today while yesterday it was going nuts. I did add some more random waits and random scroll behavior. So it goes to a person's profile (via url). It waits a bit, scrolls down their feed a random amount, scrolls back up to the element it wants to interact with, then clicks it. interacting with 100 posts/users after an hour is obviously not ideal, but it's something!
