I've came across the posts of a user from review queue.
Those are terribly bad questions, taken out of context, lacking even the understanding of Java. But all of them have upvotes, and comments referring to some facts that are not included in questions.
It's very suspicious. It seems that there's a few users from some programming class, that have started using StackOverflow as internal learning help forum.
Is it a separate case, or it's becoming a serious problem here?
