Never short naked, how can they be so stupid.

They never read the history of Jacob Little, even Nicholas Darvas mentioned he made a lot during short squeeze in the 60's.
They are arrogant, why don't buy insurance when your losses can be unlimited.
Again and again, making money in the market is about controlling risk, not how much you make.
I can only say they are very stupid for shorting naked puts without holding any securities.
