Let's imagine the following rather common scenario:
- I find, on another site (not PSE), a fun puzzle and its solution
- the puzzle and solution are clearly linked, so there's no way to link to one but conceal the other
- the puzzle is interesting enough that I want to share it on PSE.
There seem to be three possibilities here, none of which is really desirable.
I post the puzzle here on PSE without including a link to the site where I found it.This is unacceptable as it would violate the plagiarism policy.
I post the puzzle here on PSE with a link to the source where I found it. This means anyone trying to solve it here can find the solution online with two simple clicks. Talk of an "honour system" being absolutely unenforceable and therefore so much pie in the sky as far as I'm concerned, this would encourage people to game the system for rep.
I don't post the puzzle on PSE at all. Then PSE loses out on a great puzzle.
I would like to suggest the following fourth possibility:
- I post the puzzle here without a link initially. Once it's been solved and the race to answer it and get the pretty green check is no longer on, I edit the question to include attribution.
Would this be acceptable according to site policy on plagiarism?
Note: throughout this discussion, let's assume that copyright violation isn't an issue, e.g. that the site being copied from has the same CC-by-SA licensing as SE. If this were an issue, then there's no point having this discussion at all, because no community-crafted PSE policy can nullify copyright law. So I'm assuming that copying with attribution would be fine, and that the only possible issue at hand is that of plagiarism.
