What evidence do you have that this is a spy? If you have evidence, you need to say what is in order to make a substantive post. If you have no evidence, then this comment is a smear and breaks the site guidelines badly. In that case please read https://news.ycombinator.com/newsguidelines.html and stick to the rules.

Edit: you've posted this sort of flamebait at least once before: https://news.ycombinator.com/item?id=26643049. This will get you banned here—we don't want this site to become nationalistic flamewar hell. No more of this please.

just because they chose to use Chinese names, doesnt make them less American. Are you suggesting non-Chinese Americans cant be spies?
