Have a character send in Daily Prophet articles about the adventures (or misadventures) of another magical society figure. This could be anyone from a dragon tamer to a plucky but downtrodden debutante. They start out semi-anonymous and rely on pseudonyms, but with context clues it's easy for readers to piece together who they're really about. The adventures keeps getting published and readers start to be invested in the ongoing series and waiting for the next installment. Little do they know, the columnist is actually the same person the columns are supposedly written about, and most of the adventures are either entirely faked or greatly embellished in a bid to increase their social capital/get famous.

Obviously it all comes out sooner or later for scandal and drama purposes, but so much threadding potential in the meantime (and so many DP articles for us to run~)
