Zenos,
Please go to the website
http://www.419eaters.com and look under the Main Baiting forum- you don't have to join to see this thread.
Look under all posts by Sandra Rosemary.She is an IP operator who has been handling many of these scammers from Lagos. These criminals have learned how to tap into the relay system in order to place mulitple orders like the ones you friends have gotten.
They should not go through with it. If they have been warned it is a scam, and still use their credit card, they could be implicated in the fraud.
These guys are not stupid when it comes to designing ways to steal money.
They have the equipment and knowledge to do it.
Here in Canada, my local bank was taken for about $4,000 in one day because a hig tech criminals placed a "skimmer" on the screen of the ATM.
It scanned everyone's card before each transaction and then was used for mass withdrawals.
No one noticed the skimmer because it was made to look like part of the machine.
Tell your friends not to try and figure out how it could happen- it will.
Please do whatever you can to protect them before it is too late.
