Fine, and in that case you could have introduced the problem by saying something like ...
In a private email, I was asked the following question ...
... question ...
Of course you don't actually _have_ to reveal your source, but by doing so, at least you dispel the false impression that the problem is of your own creation.
On the other hand, if someone (such as myself) asks you for the nature of your source, it don't see why you would choose to withhold that information.
>currently suffering a derth of actual math problems.
The problem was a good one, but since I felt sure that it wasn't a problem originated by you, I wanted to get some idea of the source before committing potentially a lot of time and energy towards an attempted solution.
Many of the questions you ask are valuable for the group, but unless the question is of your own creation, I think that you should give some indication of the nature of the source when introducing the problem.
In any case, you finally responded to query about the source of the problem, so thanks for that (although getting you to reveal that information wasn't easy).
