How to detect/protect against spying/attacking projectors?

Never had it happen, but it's nice to know in case. I don't yet have AP ability (otherwise I'd pack an astral Glock and shoot him).

These ppl are a minority and end up attracting negative entities (demons, bad spirits, etc). However there's nothing to stop them from building a protective astral shield. Some say god will deal with it but I don't believe in one.

Then believe that your higher self will do something about it.
Either way, you can believe something will protect you... and that very act of believing initiates the protection.

Seconded.
Negative entities are very few and far in number, if you're feeling uneasy, try doing the 'white light' experiment to protect yourself. As long as you believe, it will be ok.
