For me, I think it became prominent when the Dear Marcus forums first appeared. New members (1 to 5 posts) who posted a problem there are routinely spanked by holier than thou types who would almost immediately admonish them as bashing CW - whether the OP's issue is valid or not. These 'spankers', as I call them, aren't contributing to the conversation one bit. It seems that this attitude is carrying over into the other forums where an OP starts a thread and leaves out helpful details or has not well thought out what they are trying to say - and instead of trying to help the OP with leading questions to get more details so that they can be helped, the OP get spanked/admonished into silence and/or the thread gets hijacked.
I would be OK with the admins physically deleting such posts (especially from the Dear Marcus forums) that do nothing but admonish the OP for starting the thread - and to do it without comment.
Maybe when folks see their OP-bashing replies disappearing it'll persuade them to refrain from posting them in the future.
