why do people keep unfollowing me on Instagram?

[531]

i post at least once a day, maybe twice a day every once in a while, and i usually get 25 to 60 likes on every thing i post, and usually i follow everyone back. so why do they keep on unfollowing me? maybe i like too many pictures? maybe im always following at least 5+ people a day? idk someone help cuz its hurting my self esteem

These people are not looking to you for more clutter. If they are friends in the flesh, less junk would be great. If they are online only, then so what.
