They seem biased to me. A friend of mine who's doing an ICO told me that they paid 10ETH for 5 quality ratings and that's that! I noticed that some ICOs with good project, team, and good social media presence are struggling with getting good reviews.
With all that said, should it still be a factor to look at when investing in ICO?
ICO ratings is still one of the best basis if the ico is good and will have a good chance to be successful and we all know that when the ico have a higher ratings it has chance to be successful but investor should also consider if the ico have a good team.
