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?
Sometimes i choose a campaign with high ICO trust rating but still there are campaigns that having high trust rating that scammed to its participants and it's really difficult for now to find a better campaign that is legitimate and pays the effort of bounty hunters.
