When Worldbuilding was freshly minted, an occasional newcomer asked a question, received an answer, and immediatly Accepted that first answer, minutes after asking. This drew several patient comments explaining some reasons why we don’t do that around here. After a few occurrances, it would draw one lengthy comment but others would not add to it. As time marched on we left ever shorter comments, and now it’s down to a terse “please don’t” as we are tired of explaining it. That's unfair to each newcomer who has not heard it before, and all the good explaination are in comments which will never be found again.
So, I’d like to make this meta-post a place to post these good well-written reasons, one last time. Then, we all can include this URL next time along with “please don’t”. In fact, here is boilerplate to paste for such a comment:
Welcome to Worldbuilding, if nobody did that already! While every Stack Exchange site has its own distinct differences, Worldbuilding is “more different” in some ways. In particular, you ought not Accept an answer before waiting at least 24 hours. A full explaination can be found on [this meta post](https://worldbuilding.meta.stackexchange.com/q/5023).
Having it tagged here under help-center should also make it more discoverable where newcomers will read it.
