Trustpilot is probably the worst website to check reviews. Overall, when I started shopping, the first website that I discovered was asos.com. I saw many people recommending asos as one of the best website to shop but then I saw Trustpilot reviews and I changed my mind. A few months later I decided to risk and order clothes and seems I was wrong, asos is a very good website despite the fact that their Trustpilot is red.
Makes perfect sense. It's actual name is Trashpilot. They allowed a site like 1xbit to flourish thanks to so many fake reviews for quite a while and proceeded to remove those fake reviews later on thanks to public demand.
Bitcointalk is way better for checking crypto gambling site reviews when compared to Trustpilot in comparison if you ask me.
And still a lot of people go to Trustpilot before they test out a new website. In the very beginning, I did the same but quickly discovered that is actually a useless site. For gambling sites, they are some great casino review pages (like btcgosu) that you could use to check if a casino is legit or not.
