I'm thinking of doing some freelance editing, and a thought occured to me- scammers are all over in the freelance world. and a lot of the scams don't even violate the contract. here are some examples: http://accrispin.blogspot.com/2012/09/guest-blog-post-7-freelance-writing.html
Could payment channels be used by freelancers of all types.. for milestone-based payments, or pay-per-revision, or pay-per-hour, or whatever?
edit: Forgot the shameless plug.. If anyone needs any video editing done I'm available :D My videos are here: https://www.youtube.com/user/kvidal88
