A quick search on Facebook reveals that thousands of shoppers have been fooled by the scam, and joined bogus events on the social network. At the time of writing, these have not been shut down by Facebook’s security team and still pose a risk to unsuspecting users.

Bogus Tesco events

Tesco customers are being tricked into believing that they must join the Facebook event pages and follow a series of instructions to qualify for the £250 gift voucher.

Of course, following the instructions on the bogus event pages does not garner you a gift card. Instead, you are helping earn money for the scammers by driving more traffic towards their online surveys and granting them permission to post messages from your Facebook page.

If you’re one of the many people who fell for this scam, please check your Facebook page to ensure that you are not spreading any messages to your online friends and ensure that you have revoked any Facebook applications, events and “like”d pages that you are uncomfortable with.
