I host people's builds all the time, repainting, burning, and marching zombies through them.
If you think that makes me a thief, with all due respect, take your warped and confused definition of stealing and shove it up your... nose! Haha. I got that joke off of NPR. Sounds like something Al Gore would put in his movie on global warming. Like that frog that sits in a pot of boiling water until someone rescues it. Haha. Ha.
No, but seriously. I'll host who's builds I want. I realize I don't have a public server, but if I did, chances are, you would see me marching zombies through your build.
If anyone asked me who built it, I'd tell them you did, but if they assume I built it, and don't bother asking, then at worst, they'll look like a fool when they join your server and say "Hey thats Wedge's build!" and you respond with "No, its mine, he's just hosting it." But judging by some of your response, you would probably say something along the lines of "No, its mine, Wedge stole it!" rather then give me the benefit of the doubt, and checking first.
Oh, sorry, I seem to have forgotten that vigilante justice is the way of the Internet.
