Interesting thing is, you give yourself credit for total ripoffs. You didn't even touch a vertex on this one. You just deleted the rest of a model and left it like that, floating and uncentered.
Sure, this might be useful, but usefulness should not be exploited the way you do it. Some people take weeks or months to make their models, while you just rip them off for 5 minutes and upload them like your own. I don't think that's very fair to those who actually know how to work with vertexes and polies, while you obviously don't. My opinion is, that all those ripoff should be rejected or transferred to the Blizzard account at best. Remove your name from the credits since you did exactly nothing on it. Post your useful ripoffs on the forums and stop flooding the model section with models you didn't even touch and learn to model first, before uploading models (some people may think this is self-explainatory). Until then.
