Jake Hard Tagged Peter in a post. The post itself was not at all related to Peter however it still got shared on Peter's wall automatically due to the nature of Hard Tags on Facebook. Peter told Jake to just use a "Soft Tag" instead if Jake wishes to show Peter a post in the future that's not related to him directly.
