@Emmie @Temperche might need to add that the exception is implicit. we've always argued that way before we knew this FAQ. until it came to our attention we just weren't sure because, well, we're no lawyers, duh :)

IANAL but: researching this topic was indeed a task during the first year of the project. The German implementation of DAC7 (the PStTG) includes an exception for digital black boards like flohmarkt. The criterion is that there is no formal form of forming a contact on the platform itself. Here's the official statement (see 1.1) https://www.bzst.de/SharedDocs/Downloads/DE/Digitale/_Plattformbetreiber/FAQ/PStTG.pdf?%5C%5C_blob=publicationFile&v=3
bonus: you'll will find many more hillariously unpronouncable words in this document.
Does your EU-country has exceptions?
