I am not sure about how implementation of EU law works. I can recall one EU member state that was blocking aid for a non-EU state when all other nations voted in favour. Only when they received some benefit for their own state did they allow the bill to pass.
It works the way I wrote to you, the big ones impose laws on the small ones as it has always been the case. Although the small ones sometimes ignore the big ones, they can't do that forever. The country you are talking about is Hungary, the black sheep of the EU in everything, but that is a completely different topic.
If the laws are not ratified across the EU it means there is no universal consensus between EU nations. In that case it could be down to individual states to implement their own policy towards mixers.
However, this forum is based in the US, there is an admin who is a citizen of that country, and the position of the EU on this issue is not too important. Of course, for each individual, violating the laws of their country can have consequences, but for me personally, as someone who lives within the EU, it doesn't matter at all.
Even if they (EU) ban this forum and start a witch hunt, each of us should protect ourselves in such a way as to preserve our privacy and anonymity.
