Been enjoying the site for many years, but I'm seeing this more and more, and not just here. "Titular" may be more fun to type and say, but it means a title held without real authority, while "eponymous" refers to someone/thing named in a title: Batman is the eponymous hero of his eponymous show, not the titular anything.
I suggest to the judges, especially the guilty (*cough*) ones, that you start using the phrase "eponymous (not titular)" in your reviews. This spreads the correct usage, gives the impression--accurate or not--that you always knew the difference, and you still get to type "titular."
Best,
