Unsubscribing bug?

Someone made a forum topic, and I don't remember what it was about, and I had never saw the poster before. I clicked on the name to bring up their profile, and then, just kinda for a joke, I followed them, but I wanted to unfollow later. I forgot about it, until today, they posted their first instructable. I don't really want to have that kind of thing in my feed (no offence to them) so I was going to unsub. I click on the unsub button, but it just sits and tries to load, but does nothing, no matter how long you wait. I know subbing to a random person in dumb, and I see that now, but is there some way I can unsub? 
Thanks for understanding!

I've recently went through my subscription feed and unfollowed from all of the youtube creators that I subscribe to, but I don't recall having an issue...

I got the same problem to follow some authors. I click on "+Follow", but it stays on "Loading...". Once the page is refreshed, it still show "+Follow" and not "Following" as it should.
