I have a friend who deletes her account every so often as a "reset" without offending everyone she follows, is friended with, etc. It's actually a smart strategy because if you unfriend, unfollow, etc. people, some will get upset or offended and some will then use social media to gripe about it.
What she does is delete her account, and tell everyone she deleted her account so no one thinks they were targeted specifically. Then after a week or two, she creates a new one, and only adds friends and family she wants at that point.
