Is there some mechanism for preventing a two-person team from farming rep?
Yesterday, I ran across this question, which I downvoted and flagged. I then went back to the review interface, browsed around for a while, and later checked back in on the question, where I was stunned to see that someone had actually answered it with a concrete amount of code.
I've seen people answer (or attempt to answer) extremely obtuse questions before, but the preciseness of code posted here and lack of any text asking for clarification raised my eyebrows, so I immediately wondered if the person who answered the question was a sock puppet of the person who asked it (for reference: poster's profile, answerer's profile.
On further review, I'm not entirely convinced that's the case. However, looking at both users' SO profiles, they at least work at the same company. I've never seen an instance like this before, although I'm sure it's come up (perhaps not quite to this degree). So, my question is: assuming that these users are actually two distinct people, is this a case of two people gaming the system, or is it acceptable for two users who have a working relationship to use StackOverflow as a way to answer each other's questions?
Edit: I notice now that the original question has been removed.
