didn't badspot add decals that aren't originally his, or did he make that nasa logo?
Obviously if you're going to make a decal that needs to feature a certain logo, redrawing that logo would be a waste of time. But when you're doing something like a whole decal based on a Lego Minifig... Copying and Pasting looks bad and doesn't fit Blockland's style in most cases.
Sometimes copying is okay, sometimes it isn't. This is one of the cases where it is not.
