To my knowledge, I learned a lot about ICO last year and this year. If and in 2017 with a project no matter what you do about it, I'm sure it's easy to hit the soft-cap. Now, after investors understand the ICO more and more, they do not easily spend money on a project, they patience to learn and when they know it is not good, they will not invest in it.
I assume that the problem is not quite that. In 2017 there was no such amount of fraudulent ICOs.
Now there are some statistics that potential investors are probably viewing, and it is disappointing. So I'm for tight regulation in this field.
