The question "What is the math behind Qubrix Brain Twister" has had a single edit reverted and reapplied multiple times now. This thread will be for discussion of what to do with this question.
The question has been locked and deleted. I agree with Dan (with the caveat that users of the SE network are required to be at least 13, so not quite all ages). quanta's edit was out of line: substantially changing the meaning of a question is defacement, whether it was for a good reason or not.
Isaac is certainly correct that the question would not mean anything without a reference to what problem game was being asked about. Thus, in nearly all situations, his position would be the right one, and indeed before clicking on the link I agreed entirely with him.
However, after clicking on the link in the question, I think there is certainly an argument that the link should be removed, since the game evidently involves pictures of quite scantily-clad women. IMO, links to NSFW content should be removed regardless of whether it is relevant to the question. The fact that the question requires the reader to engage this NSFW content (since there does not appear to be any way to ascertain how the game works without playing it) only underscores the need for the question to be closed. In fact I am also of the opinion that the link is spam, in the sense that this question was posted for the sole purpose of driving traffic to this site.
So, I think Isaac is right in general, but given the content of the link, I would support removing it (and, of course, closing the question, but I don't think anyone is disputing that). However, I will add that I also disagree with quanta's actions, because as Isaac has correctly pointed out, at the very least, comments need to be made to the OP and to viewers of the question explaining what is going on and what each person's reasoning is, and certainly leaving behind the nonsense question "What is the math behind" is not correct.
The question should be restored to its original, un-defaced state. If it is spam, it should be flagged as spam and dealt with as such, but defacing the question (editing it in a way that is clearly against the original poster's intent and in a way that makes the question into nonsense) is an inappropriate use of editing privileges.
edit: I'd suggest that people please upvote my comment there about reading the edit history. The question is now likely to get closed as not a real question—the defaced version is certainly not a real question, but the original was at least interpretable.
The link contains sexually suggestive images. There is nothing wrong with how the question was phrased nor is there any reason to assume it is spam. I think math.SE should be open and respectful to people of all ages and cultures. This is why I downvoted and flagged it as inappropriate for the community.
