Yes, for when record companies claim my original content. I don't deal with this every day, but when I do, it's a pain in the but. I have heard stories about some channels having to deal with this so often that they just decide to give up.
It's a multi popup window process. Most of the windows only require a few clicks, but the last window requires an explanation about why you are disputing it and a digital signature (just your full name). It would be great to at least have a canned explanation and digital signature channel wide for the last popup window. Or even better, It would be great to have the ability to save templates if you have different reasons to dispute the claim and different uses needing to enter their digital signature. I know a lot of people deal with disputes and not just copyright disputes. If you can do help them out, I'll bet the market is pretty big. Maybe you could have 3 tiers. Free users get just a pre populated explanation on the last window, pro users get to take care of it with one click on their video list page, and the higher tiers get to do it as a bulk process.
What do you think?
