Well, I guess we need to forget about ICO, they are gone long and the credibility of their projects has been lost. Does have any ICO can still be trusted, I'm so doubtful about that.
But in my own experience I don't believe too much to a ICO ranking or rating website, I experience it before that in order for my past project to be listed they need to get paid which is normal, and then there's a rating that we saw after our listing, I immediately ask that person who sent a review because his LinkedIn profile was there and he said, in order for him to remove such remarks we needed to pay him 1.5eth that was 2018.
It is likely that person what to scam you...I certainly found that some project reviews or feedback has been manipulated, paying people to do the positive reviews for the sake of having money. This is the reason why I don't just consider reading their feedback instead, I go checking and digging their history as this will tells us how they could perform for the incoming.
