Culé de Celestial Empire
I'm sure the socios had a little black market going on, but this is a simplification done by the media. It wasn't only the socios.. In truth it was never hard to get tickets for the neutral and away ends to begin with.
UEFA doesn't allow tickets to be sold to nationals of the visiting team, but they leave it to the home team to enforce this rule. And Barca does that by merely checing the credit card origin that tickets are bought with.
I asked my friend who travelled with a group on how they managed to get in. She said that they just applied for Spanish credit cards and then bought the tickets online normally for listed prices. This was apparently known as a "Plan B" among the entire Frankfurt Ultra scene for a longer time, whereas Barca seemed oblivious to this because normally there's never such a large amount of people that abuse these security holes.
Now there were of course also many cules near the Stadium selling their tickets, but this alone could have never amounted to over 25.000 home/neutral tickets sold that way.
nd Frankfurt fans are not exactly the demographic that is able to comfortably pay 300-500€ for a blackmarket ticket after already paying for the travel. 90% of them are your averge poor millennial, just more organized and determined..
Now you mentioned it, I think the fact that Frankfurt fans took up entire blocks and sections of Camp Nou, not just some individual seats scattered around the stadium here and there might indicate they bought their tickets en mass from somewhere other than some socis and Barca fans online or outside the stadium (never saw many selling tickets outside Camp Nou anyways).
Do you think Barca could have done anything to prevent those Frankfurt fans of applying for Spanish credit cards and using them to buy tickets? I don’t know, checking the billing address of all credit cards used to buy tickets, if it is a German one, decline the sales?
Before the game I almost thought some of the measures the club took was beyond necessary and could be considered discriminatory, but I guess after this fiasco, the club will have to try everything, and I have no idea what everything is, to prevent this from happening again.
