[quote=mike92104]Have you tried reporting it to your phone carrier? They may be able to track them down and deal with it.[/quote]
There’s really nothing you or the carrier or any authority can do as it’s easy for the scammers to just move their virtual presence around. It would be like trying to block someone from sending you snail mail from Nigeria. You could even probably get the postal carrier to throw away anything with a Nigeria return address, then the sender could put an Australian return address, or even send it to Australia or Iowa first and then have someone there send it to you, except this is easier to do on the Internet.
