How to mass follow instagram?

Question

API

In general, this is just a question for general development. The API limits the number of requests to 20 per hour.
If you do it not through the API, but somehow else, then you get the same rake, but in the profile, the account is spinning alone and requests come from it, because there will still be a restriction. But at the same time, there is a lot of software that turns subscribers. How?
