"Probably a german address in the imprint."

Just any adress. Their point is, it needs to be an physical adress - so in case someone wants to sue the website, they have somewhere to send the physical letters to.

In other words, many people got expensive physical letters, to make it in general easier for other people to send them expensive phyical letters.

But yes, as far as I know, this only affects germans. But once we control the EU, who knows.
