The subreddit have as description of their chatroom Bergbau Macht Frei, which is a wordplay on Arbeit macht frei, the words written on the gates of Auschwitz meant to defy prisoners of concentration camps.

According to @selsta, u/usrn, admin of /r/moneromining, refuses to take down the phrase. This is unacceptable, we should remove any mention of that subreddit.
