While I'm generally on board with this principle, I felt, given the nature of the conversation, this was a particularly egregious instance. Besides, sometimes new users can use a reminder. I'm generally not a fan of absolutist rules as they always tend to break down in some corner cases doing more harm than good (though of course we can disagree whether this was such a case). Either way, thank you for your reminder to my reminder :)

There's also the uncollected-garbage problem, which this case is a good example of.
