We have an attribution policy for non-original puzzles. Our site-specific custom close reason reads:
This looks like a puzzle you found elsewhere. For content you did not create yourself, proper attribution is required. If you have permission to repost this, please edit to include (at minimum) where it came from, then vote to reopen. Posts which use someone else's content without attribution are generally deleted.
I've always been confused over whether statements such as "I got this puzzle from a friend" or "I just have the image" are sufficient attribution, and I confess that in this case my close-votes have been inconsistent. (Of course it is sufficient attribution to say "I got this puzzle from a friend, here's a link to where it was originally from". The point of this question is for cases where the entire attribution is "I got it from a friend" or similar)
For recent puzzles (e.g. What's a general method to solve this calculation puzzle?) it seems that the answer is "yep, sufficient attribution". There's nary a close-vote there, and two answers (granted, one is in the comments) posted after this comment exchange:
What is the source of this puzzle? – Rand al'Thor
no idea, a fellow mate asked me to solve it – Hmmwell [original poster]
I've seen similar scenarios play out over other questions. However, when an old puzzle (A 4x4 grid puzzle with one missing number) was bumped by an edit, I saw a different policy in action, the events preserved in the comment section and edit history. Crucially, after the OP edited to add a link to the image they had, this comment exchange occurred (emphasis mine):
That's not quite what's meant by "citing the source". The point is that we need to know where the question comes from. While we're at it: do you have the permission of whoever made the puzzle to reproduce it here? – Gareth McCaughan♦
@GarethMcCaughan I understand, but I don't know anything about this puzzle. I just have this piece of the image. It has been circulated among some people and I don't know its origin. – 01000110 [original poster]
Ah. Then I think we have to close it; sorry! (For all we know, it may be a copyright violation, which would be illegal; for all we know, it may be a still-ongoing competition, which we have a site-wide policy against.) – Gareth McCaughan♦
The question was later re-opened once the original source was located, but that's besides the point
Wait, what? That's not what we're doing now!
It seems that policy/practice may have changed in the intervening time, turning the answer to my title question from a "no" to a "yes". Frankly, I would prefer the answer to be "no". So I'm opening this up to discussion: Is "I got this puzzle from a friend", "I just have the image", etc. sufficient attribution for a puzzle?
