I came across this question on Stack Overflow that starts with:
NOTE: I'm also offering a bounty of 50 to 100 reputation on this problem. While I am unable to offer a bounty via StackOverflow due to my lack of reputation, I do have some reputation on Math.StackExchange that I can offer. If you can help me answer this question, I will pay you the bounty on the Math.StackExchange website.
That doesn't seem right, as the bounty would have to be awarded through an unrelated question on Math.SE. Should the note be removed from the question? What should be done if they proceed with this arrangement?
