So I found this bullshit on Reddit. Indian scammer ‘wants’ gift cards as ‘ransom’ so that they can stop bombing bad reviews.
That is pretty bold. As least they are up front about what they want. 
How do you know their Indian?
Not 100% sure. Could be a troll too. That’s why I’ve put certain words in quotes. But I’ve actually seen scammers begging/ransoming like that. But if you noticed one thing, the bad reviews seems like an attempted sabotage.
