Ok I think I know what amiga1200 is talking about - took a few reads.
I think he is angry about core functionality about the site. He would like a system where raw scans can be uploaded easily, catalogued, and credit given to the scanner. This would allow for a centralized place rather than having to rely on people's personal "dropbox style" accounts.
I think everyone would welcome all these types of massive changes, but I'm not sure why he's going about it shouting and ranting.
To get back on topic, we can't stop people stealing/selling on ebay/re-uploading covers. But, If EVERYONE knew this was the site to come to for covers, the market for re-uploading/selling etc would be greatly reduced. Perhaps someone who's good at writing could write up an article to submit to places like IGN and Kotaku etc, to see if they would write up a story, directing retro collectors who like pretty cases to come to this site!
