both of these conditions must be fulfilled in order to delete the PP:
some months have to pass (e.g. 4 months) AND the player must have played a defined number of consecutive matches without getting a PP (not neccesarily within these 4 months, but before that number of matches wasn't played, the PP won't expire either)
What is left is to vote for the number of months that have to pass and the number of consecutive matches that need to be played.
In this thread you will vote for the number of months!
The poll is open for one week.
