Why would you want to remove a follower? Someone asked this question in the Hub help forum. As sofs said, if someone is cyber-stalking you, report them to the HubPages team immediately.
Do you think this hubber is somehow, not sincere in his followership (I just invented the word 'followership') of you? In other words, to you interpret the 'follow' as somehow sarcastic or baiting?
Do you not like their political and/or social views -- do you find this hubber to be a bit of a verbally aggressive "reactionary"? I ask these questions because I'm curious as to why some people have been inquiring about how to remove followers.
You know, Real_Words, you may think I'm being sarcastic as I say this (but I promise you I am not), but perhaps following you and getting exposed to your writing and your presumably much more sensible, level-headed viewpoints, might serve as a civilizing influence on this person.
Good luck and I hope everything works out. You really look bummed out about the matter in your profile pic. Kidding! :D
