I might be asking too late, but what's stopping someone from: 1. Identifiying hijacked accounts 2. Forking to GitHub 3. Waiting for the inevitable ranking change 4. Handing over the project to the owner when/if they are identified. I realize there's a good deal of handwaving here--particularly at 3 and especially 4. But, is this a bad idea? Seems like 4 can be replaced simply by the owner reforking, too.
