Reminds me of the nightmare that descended on Steam when they opened up Greenlight to nearly everyone. Great in theory, but in short order the service was drowning in low effort garbage, asset flips and downright scams. Eventually they had to up the barrier of entry a little again just to get some sanity back. Or just look at the wasteland that is the Play Store on Android. Any marketplace that's globally accessible needs to have curation and a high barrier of entry, or it will be spammed to death by these people. Of course, Amazon has no motivation to fix this, being a monopoly. They get paid either way.
