A part of my post title keeps getting deleted does anyone know why that is?

I posted Naked (American Cast) and the Naked part keeps getting deleted why is that?

Censors/filters probably. It's been known for a while that the site has overactive profanity filters that make themselves a pain (so many Japanese actors have hyphens in their names because a common component in Japanese surnames happens to have a swear in it...) so it probably censored the title thinking it was explicit.
