I agree with the number one, I often choose the first project on the web and read the concept from the project team if I think so. if the number two is the twitter / facebook folowers problem, I think I can buy it, if number three I have never seen it from ico rating because it's only for assessment.
a lot of ico rating websites at the moment, I recommend to see the ico bench.
this is very decisive, and not all of these web sites are honest. I hear they get money to add their ratings.
