Also people write fake reviews (both positive and negative) for little money. Creating such reviews is the part of SMM teams task. If anyone wants to build more or less real vision about someone based on Trustpilot rating, then I would advice to skip most reviews written by an accounts that has only 1 review and that a written during a specific period of time. For example there was a period when during week or even month only 1 new review appear, and all of sudden appears bunch of reviews written during 7 days. Such reviews are 100% fake. Besides, nowadays people rarely share positive experience on the internet, people prefer to share experience only when they had trouble.
Some people write fake reviews for money we all know that, which can make sites like Trustpilot less trustworthy. Checking reviews by looking at account activity and sudden increases can be a good idea. But remember positive experiences might not be shared as much online. It's important to be cautious but also understand how people behave online when reading reviews.
But what's the point is in it? They will get paid for writing fake reviews but with few fake people trying to defame the crypto image won't help when they have loyal customer base with valid evidence to support their claims and have been paying smoothly to the gamblers with big money also.
