I posted an answer to How to balance/time a campaign where a player character is the final boss?. It was deemed off-topic by the mods and users decided to down-vote it, according to the comments because the question was unclear (which in their opinion makes for an unclear answer, regardless of actual content of the answer).
I don't agree with the opinion that you need a clear question to frame-challenge it's very clear premise, but ok. Enough people thought that a frame challenge is off-topic. To quote a mod:
Notably, this answer is not on topic to the question now that it's been clarified.
So I came back and lo and behold, guess what has made the top-voted answer, with no comments on how off-topic it is? Yes, the very same frame-challenge I posted 5 hours earlier. Basically, an answer that says "I did what you ask, RPGs are not made for this, don't do it".
Is it better formatted? Sure. Is it better written? Maybe. Does it have an extra section on mitigation? Sure. But I guess in the 5 hours in between both answers, the same basic frame-challenge content suddenly is on-topic.
There even is an answer that seems to have no experience at all. None. And it does not seem to have gathered significantly more down-votes or "off-topic" comments than all the answers from experience.
So what happened here? Can anyone explain the voting behavior to me? Why is the same frame-challenge to the same question suddenly on-topic 5 hours later?
