How do Ты get rid of a fan?

1. What ktichenor said.

2. This is extra info: to block a person from inboxing, Ты wait for them to Входящие you, press 'block user' on their message, then all of the messages they send Ты will be sent to your trash.

I think Ты go to your Фан Список and click on the red x Далее to the person's Профиль pic to un Фан them but blocking a person that I don't know, sorry but I hope this helps.
