I asked this question about the legality of Islamic translation and tagged it translations and quran; and the moderator flagged it as better suited for the History site as its political/historical.
I cross-posted the question to the History site; it got an answer which I cross-posted back and explicitly attributed; the moderator says that it violates their cross-posting and plagarism policy and shut the question down.
First I don't see it as counting as plagarism; essentially I'm quoting as I'm attributing to where it came from and who wrote it.
At worst - one can say that the answer should just have been linked; or I should have asked to have the question migrated originally; so the question of cross-linking an answer back doesn't arise.
But one rather gets the feeling that this site is not academically orientated - though it explicitly says that is in its site-help:" and those interested in Islam on an academic level." Doesn't Islam include its history, and its theology? Perhaps that description should be modified if this is not the case?
