Follow / Unfollow trick



we need to create a service to check for users who constantly follow and unfollow specific accounts.
The problem we are facing is that due to the api limits, it seems impossible if the user has way too many followers.
A user with around 5k followers takes around 2 hours because of the constant rate limit forcing to wait. Is there anyway to get all of the ids in one single call instead of having to “move through pages” with the cursors.
Any other approach recommended?
