It's not much of a spoiler to me. The name Marley isn't mentioned until the country is formally introduced to the story. Until then, it's just a name. Anime-only viewers won't know if it's a person, a country, or something else. And people reading the manga pages of the wiki are already expecting that it will cover the latest arc so they'll know what Marley is.
