I would imagine most people aren't obsessed enough to be running GinaBot :)
Even if they are, if it isn't a friend you are not making a statement about why you unfollowed them. Their content just isn't of interest. I unfollowed somebody yesterday on Steemit.
GinaBOT is well used by many and by you I believe! I want my information on the go and its one of the best tools on offer.
There's a couple more I'm thinking of purging, no reason to keep them there if there's nothing of interest to view.
