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?
I will never trust what anyone else says to me about a coin, when you realize the power of money and the fact that everyone has a price that is when you start to learn to do things yourself instead of listening to what other people have to say and investing your money accordingly. the only research i trust in this market is the one I did myself.
