IMHO the blame rather lies with our politicians who are unwilling to take the steps necessary to cut the baddies off from the Internet. Let's see just how fast India, Pakistan, Turkey and other scammer hotspots clean up their act when the US+EU threaten to cut them off from the Internet and SS7 unless the scam callcenters are closed down for good... the amount of corruption regularly exposed by scambaiters on Youtube is insane. Billions of dollars of damages each year [1] from that bullshit and our politicians don't. fucking. care.
