Does anyone knows how to Удалить a club???

Ты can't Удалить a club once it's been created, but Ты can unfan it.

Ты can't Удалить a club once you've created it. If it's reportable - e.g. if it's a duplicate of an existing club - Ты can Сообщить it and maybe the F4 will merge the two. Otherwise Ты just have to ignore it.
