Scam is bad and all people want to avoid that scamp attemp in ico or other but its not that easy to make us stay away from fraud.
Easy to say but difficult to do. Scam can not be avoid just by checking the whitepaper since whitepaper and roadmap can be made so easily by expert to cover their scammy project.
I think menlo.one can help you with that. It's a platform that will serve as a review site for any upcoming ICO. The good thing about is that it can't be corrupted unlike the review sites we have right now where an ICO just pays a certain amount of money to get a +5 review.
