TrustPilot is complete garbage. Reviews aren’t vetted and it’s really easy to manipulate their ratings. A company can go from having a 1-star rating to 5 stars overnight. In fact, that seems to be the case with your copycat faucet. An early snapshot from the Wayback Machine shows you previously had a 2-star rating.

On average your website receives 1 or two ratings a month, most of them bad or average. However, there are a several times where you received more than a dozen reviews within the span of a couple days, most of them being very favorable. Clearly those are not organic reviews, yet it’s the reason why your site has a decent rating of 3.9 stars.
I also see from the replies you made to your reviewers, you’ve been spamming the same Free Dogecoin blog post for many years now, even when it was irrelevant to the review.
