I think the current ICO rating sites right now are corrupted and flawed, with the right price you can buy a good review from them. I hope the menlo project will be implemented soon enough, their guild based system will surely scrape and remove fake ICO's on the market right now.
I didn't believe this at first since ICObench was my go-to site to get project ratings, but it turns out that it's very much possible for their team to be bribed if the price is right. Hopefully, Menlo.one will live up to its promises. Menlo's CEO claims to have found a helpful system to solve issues that investors encounter like scams, false reviews, censored reviews. etc..
