Script Help for Follow/Unfollow

I would like someone to help me with understanding this script

session.set_dont_include(["friend1", "friend2", "friend3"])
session.set_dont_like(["rain", "#pussy"])

# activities

""" Massive Follow of users followers (I suggest to follow not less than
3500/4000 users for better results)...
"""
session.follow_user_followers(['user1', 'user2', 'user3'], amount=800,
randomize=False, interact=False)

Where (session.set_dont_include(["friend1", "friend2", "friend3"]) is that means Instagram usernames or this is default

Secondly, ['user1', 'user2', 'user3'] should this be replaced with Instagram username or is just default.

Thank you'll in advance.

Review the quickstart script containing set_dont_include, set_dont_like, and follow_user_followers, then check the repository's setup or API guidance for these calls. Document what the example values represent and what a user must replace; done means the script's placeholders and arguments are unambiguous.
