For those that don't know, the RMAH requires an authenticator and a cell phone number tied to SMS protect in order to cash out via paypal. The problem here is SMS protect does not work for everybody, whether it be having a provider that's not supported by SMS protect (Virgin Mobile), having one cell phone number but multiple battlenet accounts, having a prepaid or pay as you go plan that's not supported, having a cell phone that's viewed as a VOIP number by SMS protect, or simply not having a cell phone.
Offer us an alternative like using our home phone number and sending the code via automated phone call sort of like google when you tie your home phone to google voice, send the codes via email, let us use an authenticator number somehow... it was made to protect our account right? or do you not have faith in your own product? Have us sign into paypal when we want to complete a sale.
Don't let this be ignored by support, if this thread gets enough posts and attention maybe they will see they need to do something.
