Yes. I am sure someone could set up multiple shell corporations in different countries and receive all their money in crypto that goes through multiple tumblers. Sure. Regardless, this is not the board to really argue about people being compensated for their labor.
But I will say this. If a person I am interviewing talks about how they can show me the code they have worked on in their spare time but that I cannot ever tell anyone that they wrote it and it is on a different github account and blah blah blah: I am noping the fuck out of that conversation before I need to ask HR what my obligation is to report criminal activity.
