It emphasized bleached artwork however also seems to host a community of editors who like to edit Queen of Hearts tattoos onto pre-existing artworks.
Members like sbsnjznsnznzbxn at https://booru.allthefallen.moe/users/45700 have consequently been spamming those low-quality edits over here, often without crediting the original artists, first adding the original works, or locating the original works and listing them as parent posts.
