How to spot a crypto-jew?

[Soul Wings]

I understand there are "How to spot a jew" PDFs (please look at these if you haven't already, I consider them mandatory personally) which show the foundations of how to recognise a jew. However these examples given are mostly pretty pureish jews aside from the crypto jew examples which the author admits it can be harder to recognise a crypto jew.
Does anyone have any tips on how to recognise a crypto jew, aside from the features in the PDFs? Even personal experience is welcome in this thread - the more crowdsourced information the better, if you ask me.

Worrying constantly about jews isn't very effective.

Generally, if someone has a strange personality, one that gives warning signs, I avoid them. Working to strengthen the intuition will help a lot.

A strong 3rd Eye chakra and remembering to take a moment to tune in to the person you meet, instead of being caught up in the moment of conversation, will help a lot. Take a moment to sense their energy when you make eye contact. "The eyes are the windows to the soul."

I would appreciate further elaboration on this.
