Welcome to Scamwarners fredercia2010

The purchase of the prepaid vouchers is simply a distraction to give the scam creditability.

Once you have let the scammer know the numbers of the prepaid vouchers, things will turn into a fairly standard Lotto Scam.

The scam will go one of two ways. Most commonly, the scammer says there are fees to pay, such as an administration fee, or courier charges to deliver the check. Once those fees are paid, the scammer will come up with a reason why more money has to be paid, and this will keep going until the victim realises it's a scam or runs out of money.

Less often, the scammer invites the victim to travel to collect the winnings and asks them to bring cash for the fees. When the victim meets the scammer, the victim may be pressured into paying fees, threatened, or mugged or even worse.
