Remove placeholder from Explicit thumbnails and replace with brighter warning sign, see:Derpibooru for example.
For slower end users, possibly also add a text warning in the form of a red E to the left of the title. Simple, but lets users who's images haven't loaded yet from clicking on one accidentally.
