Does Stack Overflow have any mechanism to guard against "mutual" cheats?
I noticed that sometimes, when someone asks a stupid and easy-to-answer question, almostly instantly, a full, good answer from another user appears, which obviously receives a lot of upvotes from other users.
To me, it seems that this is possibly due to cooperation or collusion between the asker and answerer for rep gain. Not that they are upvoting each other, but that the answerer is a shill -- the answer was prepared in advance of the question being posted.
UPD: everybody, who thinks that it's not a problem, and all that we need - just downvote 'stupid' questions - please downvote this one for example: In a switch statement, why are all the cases being executed? Now I think it's not even ethic to answer such a questions and gain an easy rep... It is not what SO is supposed to be. Of course it's great for juniors and newbies, they instantly receive the feedback from all the people searching for easy questions - but at the same time it means, that SO is becoming a site for newbies as answer to hard/specific question has less points than answers to easy ones! I will do not do it anymore
