I've just configured mine as well.
The problem is that we tech-savvy get to know things like this but the vast majority of the population i.e.the non-tech-savvy, will not have heard about this. These people, of course, are the ones the fraudsters target and catch.
Also, the tech-savvy people are a lot less likely to be caught by fraudsters anyway.
I suppose we should tell all our friends and family about this and hope the word spreads.
I guess it's unlikely to get on the main channels' news programmes!
