Well, this explained why my Instagram engagement dropped the past month. I decided to report the problem to Instagram because of the trend and I didn't get a response back. So, I thought maybe if I reduce my hashtags to my most engaged ones, unfollow fewer people at a time, that it would help. The past couple days my post have now shown up on the recent list of popular hashtags I use and I'm now back in the game! My advice is if you find yourself in a Shadow Ban is to report the problem out of faith with a reasonable message, reduce hashtags, reduce unfollow rate or any growth tricks rate, and make sure your page seems reasonable to get off the ban. Mind you this is speculation, it could have been automatic but hey it doesn't hurt to try from my experience.
