youdontknowme see the EU's attempts to enforce GDPR compliance on US-run sites.
I can't claim to know every instance of this, but most of the ones I am familiar with all deal with multinational corporations that do buisness in Europe. IE they have corporate branches and servers in EU countries, accept payment in euros through EU banks, ship goods to European customers from warehouses located in Europe, and/or make active efforts to maintain a European customer base. Very different than a site like this where the only connection to the EU is that some people from the EU connect to it.
Of course, if someone is a German citizen and/or is in Germany when they connect to this site then they are bound by German law and can be prosecuted if their conduct here breaks it, but I can't really speak to how that might go since I am nether German nor a lawyer, let alone a German Lawyer.
Laura I need someone who has enough time
That is always the sticking point. I would be willing to devote some time to the health of this community but I couldn't do it on my own and I don't think many of us could. Maby a team of part-time volunteers could manage it but then someone needs to manage the team.
