If it's legal please let me know, because it's the only rule that I'm unsure on D:

From my experience it isn't.. You can't do auth trades on Sythe.
Ex: Selling my Barrows Pure for two Firemaking Auths.

From my experience, you can trade them over Msn and on other sites. I've sold, but you can't vouch other people for Auth trades.
(From my knowledge; there is a possibility this may not be right)

You can trade auths off site.
