What does “Flame-Free” mean exactly?

[Ruj.]

Translating some words or sentences solves al lot of questions but translating that one gives nothing more than no fire.
so.... what is so special here that it is without any flames?

It's a way of saying you can ask newbie/stupid questions without people mocking or 'flaming' you.
