Using marketplace assets in an Adult game?

My specific question revolves around the terms and conditions of using UE marketplace assets inside an Adult (nudity, sexual activities, etc.) game. UE and Unity both state you can use their engine for such things as long as it’s legal. However, Unity specifically states their marketplace assets cannot be used in such a game that involves pornography, sexual acts, etc. I can’t find any information on what’s Unreals stance on their marketplace assets being used in a game with Adult content. Does anyone know or able to point me in the right direction?
