Must give the article a proper read.
I was in Hamburg last March at language school for a couple of weeks. I was determined to get to a St. Pauli match while there, but their game was sold out (most are, I gather). There was nothing available online and everyone I asked said they were like gold-dust.
In the end I decided to go to the ground itself. The girl in the ticket office said that they did have a return but that it was in their main stand and really expensive. When I found out that really expensive meant 50 Euros I snapped it up!
Then the game went behind closed doors anyway because of Covid!
So I still haven't seen them. However, the visit to the ground was interesting in itself.
