No words.
C*nts.
I did notice this year though, when I went to the ticket office for memorial tickets last week, that they have limited the tickets to 4 apeice, and they must be registered against a seasie/membership/fancard.
Presumably it's upto 4 per card, and the tickets do have serial numbers of a sort.
I don't think the serial numbers are recorded against the purchasing card though, as the numbers are just for letting them know how many tickets have been collected, to guage how many stands they would have to open on the day etc.
As an example, the memorial tickets I have are in the 16,000 region.
