There's another variant on the Nigerian scam, although Prof. Cotton has not seen this one anywhere near as frequently. One might get suspicious about getting two or three of these in a week!
This is, unfortunately, another advance fee scam. "Winners" who contact that "lottery" outfit are told that there is a fee to be paid so the winnings can be transferred. It would seem that, if you had won "millions," that the fee could be simply deducted from the total and the net then remitted. No - it can't work that way. The fee must be sent FIRST - then the winnings will be sent. There will be other advance fees as well. Sound familiar?
At the risk of sounding repetitive, the best thing for you to do is use the "Delete" button in your e-mail program.
Now - what kind of approach ought you take to anything like this??? Remember the old saying - "If it seems too good to be true, it probably is." Millions of dollars floating from out of the blue into YOUR bank account certainly fits that description.
Consider this: Why me?? How was I chosen for this marvelous windfall? Especially since you probably DIDN'T buy a ticket for that lottery. And how would someone from Nigeria know you? Can you say spammer's e-mail lists??
