Blocking is pointless, the spam origination systems seem to be able to use multiple numbers on a rolling basis. I guess iPhone IOS added a incoming call filter api. I had been receiving so many calls on my cell that I tried some filtering apps. The HiYa app I've currently settled at seems to identify most incoming spam numbers and you can decline the calls. I think the volume of my spam calls as gone down too.
