Apparantly touts have had a field day selling forged tickets for the IOW Festival. At one point a fifth of the tickets coming in were forged. This meant it took at lot longer letting people in as tickets had to be double and triple checked which resulted in massive queues outside the arena. Some people reportedly queued for 4 hours and eventually gave up, not getting in at all.

I wouldn't bother going if you plan on buying one outside. I feel sorry for the punters.
