I agree with you that most of them don't have any quality. The question is how can you know will it be a good coin or not? Maybe we can eliminate those that don't have whitepaper and a roadmap. Are there any other ideas how to decide which coins don't have any value and we should not even bother with them?
If there is no whitepaper then yeah it's pretty much a useless project, or at least they are ahead of the point where they need to be. No point in coin distribution if there is no plan for it.
