There's no need to waste time looking for all of them. I can tell it just by looking at the website and its presentation. If the website looks like it is made by a 5 year old with tweaked WordPress themes, then you know what that means. But if its quite good then I dug deeper into each of the member's profile for red flags. If there's none getting caught red handed, I still don't invest in their ICOs without getting enlisted in exchanges first.
I am a simple dude. I find any legitimate tokens on exchanges, I trade.

It's great to hear that you are much expert regarding ICO. I appreciate your idea. Actually the reson of this post , I have caught some ICO recently with fake team. Then many people asking me how to find. So I thought to share that process how I found. It's not for investor only, it's help for bounty hunters also. I am also same to you. Even legit ICO I am not much interested to invest. But some time it's happened and I have never loss any ICO. Currently most of ICO is scam or can't reach soft cap. So better avoid now.
