just to make sure i got that right:
playing with a mixer = delete the match
playimg with a cheater = 0:1
Team A plays 20 matches overall, 6 with a mixer.
they get 6 matches deleted, have 14 matches left and are not allowed to play the playoffs.
team B plays 18 matches, 18 with a cheater. they get 18 matches forefitted (is that a word^^) and play the playoffs?
EDIT: it gets even better: playing with a mixer: whole team gets 1 week matchban, playing with a cheater:
