Has your work ever been plagiarized?
ww520: Yes, I once released a P2P product developed solely by me into GPL license.  Shortly after that I noticed another guy started another project copying exactly all the source files, and he put a copyright with his name in every single file even when there's no change in the file.  Now I was ok if he wanted to fork the project but damn it don't claim credit for work you didn't do.  I contacted him to ask him to remove his copyright and he said he's forking the project and there's nothing I can do.  I contacted Free Software Foundation and they said there's nothing I can do.  That's the way GPL works.  I swore then I would never release another GPL project again.
