A participant has posted quite a few questions which he has answered immediately. Now, while I don't doubt that this can be beneficial (he seems to be getting up-votes), it also strikes me as disingenuous. It is almost as if the purpose of the question is not to get an answer, but rather, to exposit his own views/opinions. If this were stackoverflow, then it would be more than expected that his question would have some form of disclaimer stating that he was asking the question specifically so that it would be answered (such as the edit on this question).
Is this something which needs moderation? It strikes me as against the general intent of SE sites.
