I thought it was general knowledge that these things were scams, they dont even try to sound legit.
From facebook earlier:
KFC NZ Please beware: unfortunately there is a link stating “Get $100 KFC Gift Card (limited time only) CLICK HERE & CLAIM NOW" – this is a SCAM & is not an official KFC promotion. If you have clicked the link it would be wise to consider changing your password. https://www.facebook.com/kfcnz
