There is an error here - the post should not be linked if the target has moved to another forum. However, it still should show up, but shouldn't be linked. The problem is that there is no concept of "private" or "public" forums - GForum knows that the currently logged in user can or cannot access a particular post, and there really is no clear way to define public vs. private forums. However, I've added a 1.2.0 fix for this to not link the thread.
If you wanted to take it out of the forum loop completely, you could add this right after <%loop post_loop%> (the post_moved_perm is new for 1.2.0, and won't work in previous versions):
<%if post_moved and post_moved_perm < 3%><%nextloop%><%endif%>
