This question already has an answer here:
After completing an answer to the question 'compare [something] with/to [something]' vs. 'compare', I clicked 'Post Your Answer' and the answer went live. But unbeknownst to me, a moderator had put the question on hold almost 10 minutes earlier.
How did my answer get through? Is there now a grace period of, say, 10 or 15 minutes to allow people who were in the midst of writing an answer to post it after the question is put on hold? Or was my answer saved by a glitch in the automated process of answer blocking?
I would be delighted if there were some sort of 10- or 15-minute warning on questions that are about to go on hold, so that answerers would know either to abandon ship or to get their initial version of an answer in before the wall goes up. But perhaps, from EL&U's perspective, the block needs to appear without warning in order to prevent people from posting answers (or the skeletal beginnings of answers) to questions whose value is in question.
