This script auto follows Instagram users read from a text file with some delay. The list should be a plain text file (without any headers) with username on each line in order for the script to follow them. The script follows 10 accounts in less than a minute, then sleeps for some random time between 40 and 120 seconds (see or adjust on line 44).…

#
# First install 'instagrapi' that manages the authentication process:
# pip install instagrapi
# To run the script:
# python follow_a_user.py
