phone the mark? how 1990's
Why bother going to the trouble of calling people to extort money. Isn't that what the internet's for?
Now I may be a bit out of touch, what with receiving almost no spam - ever. However it seems that a few million emails, sent at virtually no cost, would prick a few consciences and reap more rewards than spending time and money on old-fashioned methods like phone calls, as this gives the victim the opportunity to question their fraudsters.
This is where everyone else tells me that they already get a bazillion of these emails every day - oh well, there goes another make-money-fast idea!
