For my part, when someone receives a decent service, they won't go out of their way to write good reviews. But if they don't like something, they'll write nasty reviews everywhere, because they're more motivated to be heard.
This is why the number of bad reviews always outweighs the good ones. If companies don't engage with users and don't ask for good reviews, it's easier and faster to inflate and dilute them. But that doesn't mean they're bad, in my opinion.
I'm sure even good services have their haters and users who don't like something.
See it this way; two things motivate review;
1. Extremely good project offering excellent and affordable services. This type of project doesn't beg for review or try to influence it because they are true and among the best in the services they render. So, most services are just good like hundred others and that doesn't spontaneously initiate a review. So, a good project that doesn't get positive reviews need one more push or spark.
2. Bad project will immediately trigger bad reviews, because humans want to save their fellow humanity from avoidable losses.
Another category is those who aggressively pay for review and most time they don't end well.
