This may just be a silly mistake on my part.
I’ve been following Craig on Twitter ever since I started using Twitter again last year (having not bothered with it for many years). I’ve just noticed that when I view his Twitter account there is a blue “Follow” button, i.e., Twitter says I’m not following him.
One explanation, of course, is that I have accidentally hovered over the “Following” button, whereupon it has turned into a red “Unfollow” button, and I have accidentally clicked it, all without noticing that I was doing so. But that’s hard to believe.
Has any other Twitter follower of Craig found that they have mysteriously ceased to be a follower?
