I downloaded and used several apps that were supposed to help increase your followers on instagram. They asked for permission to follow (and unfollow? I guess) other users. At least one of them said only "with your express permission". Well I ended up deleting all them, but they still seem to be influencing my instagram. I see accounts on my feed but when I tap on their profile it says I'm not following them. If I follow them and look back later I won't be anymore. So far I've tried logging or, deleting the app, and reseting Location and Privacy settings, but it didn't help. Any ideas?
