The easiest way to deal with this imho is the get call blocking. Most phone provider have it and don't try charge extra. When I get a call from a number I don't recognize google it which usually brings me here and I know right away it's someone I don't want to talk to. Then I press *60 for my provider then #01# and the last call is added to my call block list.
These guys are complete idiots. "We have the power to knock off a front page listing and put your website in its place" HAHA. Good thing they called an internet marketer
