You're doing it wrong. You should look at the team and the experience they have, whether this project exists already (e.g we have Monaco, TenX, Centra, MoxyOne and many others) and none of them actually delivered 100% what they promised etc. so unless you really see the potentials on the project, you really shouldn't invest. Ignore the moon bullshit they are trying to feed you.
This is valid for both bounty hunters (because they are wasting their time) and ICO participants (wasting money).
Rating site is good for review only, not an investment advice. A proper research and knowledge about the ICO is required before investing.
if you relying only on the rating site, you can be wrong because they could pay the site to promote their own ICO.
