How do I delete a follower?

AllTrails uses following vs. friending so anyone can follow anyone else. The main reason someone you don't personally know might choose to follow you is they see that you've done a lot of similar activities and are interested in what other trails you might be doing that they would potentially like. We don't currently provide a way to block another user but if someone has been harassing you in some way please contact us immediately so we can look into it further.
