And how do you define minimum responsibility? Using google search for the picture or reverse image matching doesn't count as 'minimum responsibility'.More than the managers it's responsibility of the participants to do all that knowing managers will get paid anyway but if the project turns out to be a scam, it's the bounty whores who'd suffer.
How you expect payment for participant if ICO team or ICO itself if fake from began? Will you join any bounty if you know the team is fake & plagiarized whitpaper , steal content from others website. Is it trustable, even no one can say exactly they will scam. Will you like to buy this token or will you like to join bounty? Thats I mean minimum responsibility. We can't check their physical location but we can check on web about their face. We can't realized they will scam but we can check their website content whitepaper they did steal or not. I expect you got my point it will take max. 1 hours but it can minimized scam. Whatever I exposed fake team most of them skip with fund. So how can we believe them ?
I am not blaming only managers, I have a thread about it. Please read it :
