Beware of a costly E-bay scam related to people buying vouchers

There's numerous reviewing services out there offering Amazon vouchers, there's only so much shopping someone can do on Amazon and if you are earning a fair portion of them, it won't be long before you look to sell them. Whilst it's against Amazon Terms and Conditions, E-bay seem to allow it. Unfortunately the scammers have also found an opportunity here. There are two methods.

1/ Someone buys the voucher from you, you send them the voucher code, they leave you positive feedback (or sometimes none at all), they then claim to have had their account hacked and no nothing about the deal. Paypal refund their money because there's no proof of postage (considering it's an e-mailed item). E-bay are not interested at all.

2/ Someone is genuinely hacked by someone hacking people's accounts to obtain voucher codes but it works the same way as no.1.

It's common for them to buy loads of amazon vouchers from all the dealers on there,so keep in contact with your peers. The best way to prevent this is when it happens to withdraw the money from paypal immediately and call paypal to inform them of what's happened - they should protect your sale. E-bay won't be interested at all though.
