This is what
FT Rules say w/r/t PMs:
The FlyerTalk private messaging, email and chat systems are subject to the same rules as FlyerTalk posts. If you have received a message that you believe violates the rules, contact a moderator or senior moderator. The posting or otherwise sharing of a private communication, such as an email or private message without the author's permission, whether on FlyerTalk or elsewhere, is not permitted.
