Surely we have vigilant
geeks fanatics pedants editors who will hopefully catch those things before some time elapses, but once a cat is out of the bag, it just is. There's also the chat feed, which does not update itself when the question is paraphrased.
This brings us to my request: update the "How to Ask" block on the main site (and the relevant Help page) to reflect our policy on spoilers.
To be clear, I'm not trying to convince myself that everyone will read this block, let alone follow the policy; still, it's a nice
useless precaution to have.
