Even then if a coin goes for escrow they can scam and you can see latest in ICONOMI ICO it went highest and after that now the Developers are enjoying the ICO money giving all shit ideas and peoples are still believing them.
Of course it's more complicated. Like escrow releasing 100% funds towards devs on token distribution is bad escrow. Good release conditions is when parts of funds get released on development progress: 20% on tokens distribution, 50% on beta release, etc.
Iconomi is not a scam in anyway. You will see that soon.
