[Engrish] adult content warning [FIXED]

[nwa]

"This anime is marked has hentai"

should be "This anime is marked as hentai"

[wahaha]

I'd suggest: 'This anime is marked as "hentai" (Adult content)'.
... just for the subtle allusion that "hentai" is the western word.

Also, for the second sentence:
Change "disable by enabling the corresponding option in your profile"
to "disable with the corresponding option in your profile"
... or better: "disable in your profile settings"
