I'm looking for a solution to follow someone followers, example, I select a target user, then it follows all his followers. Do you know if there is anything free that might work for me? - If not I might develop a new tool, so I would like to ask you somethings: The only way to interact with Instagram via PC is using their API? Is there any rules that I should be aware to not get banned? Example, only follow 300 people daily or is not well known the limits? Thank you for your time.
