It's important to make the distinction between:
Non Attendance - When someone doesn't attend a game themself, however either lists their ticket on the exchange or transfers it to a friend.
No Show - When someone doesn't attend a game or list it, meaning the seat remains empty.
In my opinion Non Attendance isn't an issue, the seat still gets used, however No Shows are an issue.
Its not very clear If this thread is regarding Non Attendance or No Shows, but if it's about Non Attendance then I'm afraid it's whinging about nothing
