Read a few of those threads and I wonder if a good(?) idea would be to create a dummy AW account. Ok, you get an alias (I tend to use the phone anyway), but then if your partner stumbles across it in your browsing you could log in to your dummy account and show some 'innocent' messages.
For example, you could message some of the scam profiles with abuse and then claim to the partner you were trolling there for fun.
Or you could write some messages to prossies offering a service like driving and state explicitly you would have no interest in sex.
Belt and braces lads
