Delete someone from your Fluther?

You cannot stop someone from following you.
Technically you are in their Fluther and we can only edit our own Fluthers.

Like @Dog said. Or another possibility is to delete your existing account and start over and hope that person doesn’t recognize you. Good luck!

Your fluther is only those whom you are following. You can delete those any time because that’s in your account. You can’t delete anyone from someone else’s fluther, even if you’re the one who’s in it, because that’s in someone else’s account.

(Some thing @Dog said, just worded another way.)

And don’t concern yourself with removing people. They are not alerted and will probably never notice.

I remove people only when they’ve been inactive for a long time and I need to make room.

Doesn’t Fluther give you an option of going to the person’s profile and removing yourself from their Fluther with one click?

No. You can’t change someone else’s account. It’s not a “friend” relationship. Why would you expect to be able to control what someone else looks at on fluther—including your posts?
