The best marks never know they've been scammed in the first place, which is why the keep coming back for more.
Think the movie The Sting.
Remember right at the end when they get the cash and Robert Shaw's character was bundled out of the murder scene happy to get the crap out of there. So he's lost his money but doesn't have the plod on his tail, a sort of result.
But he doesn't know he's been stung so they can come back to him again in a year's time and try it on again.
OK, you wouldn't be able to do this to Shaw's character because he's a little bit too street smart but you would for the average man on the street.
So the orginal OP is still not convinced he's been stung which is why he's ripe for the taking again and if he didn't post here (or elsewhere) then he'd be taken to the cleaners again.
Bob - Please don't take any of this personally I'm not having a go at you to be mean, rather to drum it into your head to be very careful indeed going forward. Use the internet like you've done today and you should be ok. Good luck as well and in future please come back here if you need anymore help. We might be rude but we'll save your bacon
