I recently stumbled across this website called 'you thought we wouldn't notice'. It's a site where people have discovered copycats of either their own or of somebody's else work.
Plagiarism is WRONG!! SO VERY WRONG! You should never ever do it. To all artist/designers/musicians/writers, please be careful. Copyright your work. Its so scary to see how close people will copy your work!
Visit the website to see how bad people out there will do anything to cheat a little.
