Maybe, but the current rules are very clear that STH points are earned for holding a STH not for attending.Thats an interesting one. This works for me as I can't go to all home games. But in reality you really should only get the points if you turn up, it's the same difference as buying an away ticket and not turning up right?
I don't doubt that the club would be in contact with those who have a usage pattern/non-pattern that suggest they're not holding a ST with the intention of attending the majority of games.
