They sent me an email, asking for an honest review of a software I use.
The email read:
"Hi there, we want your feedback on FreeConferenceCall.com! When you write an honest review* on Capterra about your experience using FreeConferenceCall.com, we'll send a $10 digital gift card to the first 250 reviewers as a thank you".
I complied and wrote the review. During the process, I was required to select my country (UK) to receive my $10 digital gift card. However, I found out that the UK was not eligible. Then I selected another country, the USA, and encountered the same issue. I opted for Europe next, and still, it yielded the same result. You know what this implies... SCAMMERS!
