Bit like the war on drugs
They caught someone, wonderful. Now someone else will pop up.
I used to get a similar problem, well before Al Gore invented the internet, with people offering to employ my ex wife's worthless brother. You see, it was what she wanted to hear, so it must have been true. (Note, use of HAVE and not OF). All it took was to lend this guy £10 (whatever) and get her brother down here (more expense). Needless to say, the first £10 was a down payment, several other techniques coming into play shortly thereafter. I knew that my brother in law was not going to get a job and told her, but would she listen, never. As long as she heard what she wanted to hear, then it was absolute truth. I got her money back by going around every pub and asking everyone in it if they had seen whatever his name was and showing them all the bounced cheque. He came looking for me to give it back !! so I would stop damaging his reputation !! He even asked what he had done to get me to do these nasty things to him!
Now we have spam. All it has done is to de personalise the introduction. You still have people who hear what they want to hear, read what they want to read and believe what they are told as long as it is what they want to believe. Bit like the government believing IT consultants will save them money.
