there are lots of cases like you mentioned and so many of these new investors don't know how to become good ICO participants and the ICO who really can have requests and projects developed is very useful it has become very little because sometimes when ico finishes a lot once that is just nonsense and not in accordance with the plans in the whitepaper.
Let's not forget that what's on the whitepaper are just plans and the real thing is that these words written on the whitepaper will be tested when the tokens hit the market. Reality is, some of these ICOs won't even make it to to hit in the market.
