I did, it is easy, you just don't spy on people and have a point of contact and you're good. It becomes hard when you want to spy on people and also remain compliant with the no spying law.
Getting consent in a truly compliant way is basically impossible (it should be opt IN, not opt OUT). Though we've trained people to just accept literally everything now.
Why is opt in "basically impossible". That is the definition of consent. Ask BEFORE you do something. It might sound strange but most people really don't want their data gathered by everyone.
