There's been no such policy discussed anywhere that I'm aware of & I, as a member of FlyerTalk, would be disappointed if there were & wouldn't support such a policy.

If you find that some threads were prematurely closed, then I would encourage you to contact the moderator that closed it to ask why via PM (it's not a TOS violation to discuss moderation if its done in private versus the public forum). If the answer you receive doesn't make sense to you, then I would encourage yout to contact Randy Petersen directly.
