Hey @thomasbrod,

as a German, I can relate. It is just "zitieren" which can also mean both... And, as people posting on steemit from a different country, also two different sets of laws apply, depending on where charges would arise. So better safe than sorry, but when one respects some key factors, it is actually quite doable. But I respect the people who license e.g. their pictures under CC0 more and more, as this is the only true sharing!
