My business partners and I had a satire book published through Amazon's platform for a couple years. This past spring the book gained some viral traction thanks to Unilad (or similar site - I forget which), but that attention led to copycats submitting a takedown notice on the book before republishing our book as their own.

The appeal process was a complete joke; we had to get a lawyer involved to get Amazon to release the royalties it withheld because of the take-down.
