> I guess some is the key word. It makes sense to disallow charge backs for Kickstarters and such, because that whole premise is: You pay me a certain amount of money, and I'll try my best to get you something in return.

Sure but at the same time, fraud is fraud. If a project is fraudulent, then who should bear the consequences? That's not that simple. Ultimately, backers do pay Kickstarter, never the project creator directly.

Right if you’ve been defrauded, there is the justice system for that. Skipping it and relying on the banks,is only an option if the banks have already predetermined the winner.
