Misleading or unclear "Self" credits on shows

I have a question about credits. I've just seen a listing for an amateur podcast which discusses media, and in the credits, famous people who are subject of discussion are credited for the show as "Self", making it look as though they actually appeared on the podcast themselves as guests. I wondered if this breaches a rule? It does look misleading and unclear, showing them as involved in the show somehow when they have no connection to it.

Anyone advise?
