Note: They aren't necessarily farming upvotes, because there is also a downvote feature for not-so-great posts.
Also, Web 2.0 Calc is for posting problems, regardless of where it comes from. The point here is to learn, not to cheat. How can you assume that they're cheating ? How do you know that they haven't gotten it wrong, and just want an explanation in general?
