I have found out that Digital River, the company Turbine uses for their DDO Markt underlying billing software, has a builing in Cologne.
Since I have a meeting in Cologne on Wednesday, I do plan to go there and complain - if they let me through, that is.
If they don't, I'll write them a bitter e-mail.
I know the area where the building is; the local group of HSPs had been holding meetings not far from there for a short time.
Edit : On a more lighthearted side, I found this very interesting :
