the mechanisms involved in this so-called recreational complaining is probably displacement (see this article
http://en.wikipedia.org/wiki/Displac...8psychology%29 ) and "help rejecting complaining", in which a person deals with emotional conflict or stressors by complaining or making repetitious requests for help that disguise covert feelings of hostility or reproach toward others, which are then expressed by rejecting the suggestions, advice, or help that others offer.
having read the forum for some time, it is clear that most of the things that people complain about are very real.
