From what i have learnt previously, if something looks too real to be true, then its like to be scam, i don't want to make my conclusion on this yet, but when you're yet to get online review and suggestions about something from different sites means its probably coming in new and people are not yet aware about it or they don't trust the entire process in it, i will advise you to play safe and be careful, it may be a scam.
I think it's " Too
good to be true ", but that's right that these things are highly suspicious and likely a scam. If getting a review, he is in the right place because many users here are honest about their feedbacks, as we know a lot of them already compared to those random names and anonymous users that we see on a typical review site. It's possible that a site is not new but he is not only aware with it and maybe many of us here know it already, which makes it easier for us to rate it and make a conclusion if they are legit or not.
or they don't trust the entire process in it,
This reminds me of another saying called " Trust the process ". Maybe we find some sites shady and we can say that we don't trust their process but I think the act of verifying them like what the OP did here, is still called as a process.
