One of my sites got banned by Google... Hard to tell but it looks like, because it was ranking nicely for a very £££ term some rival company put some horrible links (Chinese, Polish, viagra type stuff) into it. If that is what happened, then it's a shame tactics like that can work. 
If I stick the same site on another domain does that help anything or is it just as bad --- either looks like a copy / duplicate content or if I do it the "proper" way with a redirect and URL move at GWT is that just going to pass the "bad-reputation" to the new domain and give it the same status ?
