In the three cases of moved topics I have seen, none have displayed the "Moved Topic" icon, wether due to Admin transition, intentional non functionality, or code error...



edit: Actually, I am a total idiot. It displays in the place where the topic used to be... unless it was split it out of a topic...

It's also optional at the time a post is moved. The admin can decide not to leave a placeholder behind if they want.
