It’s not dumb. I haven’t specified that detail even though I do have a rule on it.
The SPQR Team members do not wear masks. It goes hand-in-hand with the SPQR rhetoric on keeping the public’s trust. It’s also just being practical, as the very public and media-examined nature of their positions wouldn’t permit keeping a secret identity for long.
The super-villains are a mixed bag. Some do, some don’t. It largely depends on whether or not they try to maintain a life or civilian identity outside of their criminal activities. Hades does wear a mask, or uses shadows to conceal his face, because he maintains a public civilian identity as Dimitri Aidoneus, owner of DOA Records. Without a secret identity, the police and/or superheros would simply arrest him.
