How is this possible? I have someone under the name of register and I cannot remove them.
Sorry about the late reply, but I stumbled on this thread while looking for answers and wanted to share my findings. I hope you have a "better late than never" attitude, because I found out how to remove friends. According to this thread ...:
... blocking another user will prevent them from following you. To block someone, go to their profile and hover over the little nearly invisible gear next to the "Languages" box. This gives you the option to "Block [username]". After fiddling around with the "Following/Followers" box on my profile page, I found that blocking someone will remove them from your Followers if they are already on the list.
I hope this helps. And if it doesn't I hope you don't have to wait another seven years for the answer.
Sorry, but I don't know of a way to remove people if you can't go to their profile page. I assume it's sc_ville you can't un-follow, as I went through your "following" and they're the only page that goes to a 404. I'm also having trouble with finding this person in searches, so it's not just an issue on your end. My advice is to ask a moderator for help.
That depends on whether you want to unfollow them, or them to unfollow you. Duolingo makes a distinction between people you follow ("Following" in the box on your profile page) and people who follow you ("Followers").
If you want them to unfollow you, blocking is the only way to do that as far as I can tell.
If you want to unfollow them, go to their profile. You will see a green box containing a tick mark and the word "following". Click that to unfollow them.
I don't understand why people don't enjoy following/being followed as everything on here is anonymous, and there is no chatting aside from in these comment threads...it simply allows you to compare you progress with others, and offer small [default] messages of encouragement. I enjoy this feature!
