It was 'worldcoin'. And yes I used the term 'money' very loosely there.
Apparently the token was only offered in some countries, and in some places where it was offered, that was considered enough of a bribe to render void the informed consent to collect and process private data.
Was it free money? I recall that it was some shitcoin token paid out, which may or may not be worth something.
I could be wrong, of course.
