Cell number rotator?

Because Facebook and others want confirmation of cell phone number if they suspect a robot or someone "high risk", would it be a good idea to start a third cell phone rotator service? They (it could be Google or anybody) want to verify cell phone and account correspondence, and if the own volunteers that information to a private third party service, like "escrow", a request can be made, because big institutions understand IP address eleusiveness all to well, to have login information to verify cell phone, and re-establish a connection.
