I saw a neck massager on Amazon 338 fantastic reviews. What was odd was that they almost all had pics. attached and the reviewers had odd names. The grammar was strange also. So I started clicking on the reviewers, then it got really weird. Many of them had also bought the same, rucksack, interior camera security, party bags, air cooler, etc. They also give every product they have bought a five star review without exception.
Now what are the odds on that.
