[2019] Received In game Rank Adjustment Message

Originally posted by GoodnEvilNezha: The message is as following:

Players you encountered in Ranked matches have been identified as cheaters, so that the effect they had on your MMR has been cancelled. Consequently, it was readjusted by 'removing 88 points'. bla bla bla bla bla.......

My query is why is removing but not instead of adding?

MMR rollback occurs when players you've encountered in Ranked matches are identified as cheaters. Your MMR gets readjusted accordingly to cancel out the cheaters' effect on the affected games.
