The thing is, with one of my accounts I was following for the first time - there weren't any to unfollow so it was definitely following people for the very first time.
Maybe Twitter's update now knows when automated bots are being used? Or maybe either 5-6 minutes is too quick when you start from following 0 people, or 22 people is too much.
Seems strange though. I'm sure people would naturally follow more than 22 people even after creating a new account, and every 5-6 minutes is hardly quick.
Yeah twitter is either picking up TweetDemon footprints, or we need to tweet more to make the accounts look as authentic as possible. I'm going to tweet in Tweet Demon while I use another program to follow for a few days.
