Contrary to missinformed popular belief...
... your punishments are connected to each other
there are four steps of punishment
10 game chat restriction
25 game chat restriction
2 week ban
permaban
they are steps on a ladder
they are not separate items
if you are currently on the 2 week ban step of the ladder and are toxic again, you don't go back down the ladder to the first or second punishment! you go up!
plain and simple
Edit:
I know its not accurate. An accurate chart with all variables included would be much larger
Its mostly targeted at the people who post on these boards complaining that the perma they got after the temp ban is too harsh
