How much of a problem is this outside the US? In Japan I get maybe 1 call like this a month (always from a "weird" area code). Meanwhile everyone in the US seems to be constantly getting these calls. Surely other countries also have marks!
(I know about the scam calls to old people in Japan being a thing. Having a cell phone probably removes me as a mark)
Not a problem in the Netherlands. Unsolicited calls from companies you where never a customer of where made illegal a while back. In the last year i've had 1 robo spammer call and 1 telemarketer, so it seems to be working.
If you apply for a home loan, you will get about 100 calls per day for the first week and it will trickle away over the next two months. I still get 3~ per day. It's insane.
