It seems that one should avoid question about cyber security tools (Since it is very opinion based. But is it allowed to ask about how specific popular tools work?), no code reviews, obviously no blackhat answers/questions and I think much more things which one should consider by asking a question. Is there any FAQ or some unwritten guidelines which I should follow? I totally agree about those guidelines but would like to know more.
https://security.stackexchange.com/tour and https://security.stackexchange.com/help/dont-ask don't really answer my questions.
