I think about this a lot since I get scam calls a lot. What some people do not know is that answering these can cause more calls to happen. Some scam calls are just being sent to random numbers to just see if it is even a real number. Then they see it is real and keep calling. So it is best to never answer.

There does need to be some sort of regulation when it comes to this. It is hard to regulate though because often these scam calls come from outside the U.S. and that makes it tough to enforce any real consequences. I do not have a solution (If I did I would probably be rich) but maybe regulating the cell phone companies so they actually put real blocks in place. The are probably in the best place to do something about it all these calls so if they have a real incentive put in place by regulations then they might spend real time trying to solve the problem (This could be a thing already but I am not sure to be honest).
