Haha awesome, did something similar to this last year until I got hit with a ban. My biggest problem was when I implemented a follow/unfollow method. Started to get similar DMs and a lot of reports. I now try to keep away from that method when using my script as it puts you lower on the radar.
Another good tip: Add a ‘bot remover’ which could be easily added in python. Check if the account is active and if it’s not simply, block and unblock the account so it’s removed from your follower list. I believe Instagram even has a ‘remove follower’ button now.
