How long ago was that? It was certainly true in fairly large portions of the world, but there are plenty of places where, for as long as I can remember, you could pretty much expect to be scammed regularly. In many cases those scams would be for trivial (to visitors from wealthy countries) amounts of money, but it nonetheless often seemed like a large fraction of local economies would be driven by scamming tourists.
I think that the real recent change is that the “beaten path” of touristy areas has gotten larger.
