>It's technically easy to do. You hire a roomful of people to vet advertising, similar to how every media company did it until 2010 or so.

But it's not a room full of people. Facebook doesn't only exist in the US and I doubt that people from the US will be good at vetting political ads in Poland.

What's even worse is that at that point you're asking Facebook to censor political ads based on what Facebook thinks is right. Do you really think that Facebook wouldn't be labeled biased and there wouldn't be even further demands from them?

This is easy to do in the example of a health clinic, because there is a right and wrong answer, but in politics that's not the case.
