-400 ELO Just for fun


09/24/2018 I had 1820 ELO, on next day I have 1401. I want to know why my 400 ELO disappeared. I did not receive any notice about this, people I often played with were not banned, but I was taken away by ELO. I could not lose 2 levels of facets because of cheaters, there can not be so many of them that I would lose 400 ELO. I’m asking for clarification.
