The tag guidelines were last updated
Why Tags Matter
Derpibooru has a lot of different types of content and almost any type of artwork and most types of meta content are allowed, thus, the use of filters to only see that which you want to is essential. Tags are a necessity for filtering to work, and rating tags are the most important because they capture large categorical distinctions of content type.
These are the most important tags, which you should start out with before considering others.
The rating tags
These special tags group content into broad categories. Images require at least one, and non-safe images can have one of each non-safe type (sexual, dark, and gross).
Note that images only reach a higher rating once they have something in that rating.
The safe rating (cannot be with any other ratings)
Safe for work and children.
Pieces of official MLP content without edits, and only reasonable cropping/animation loops/etc., are always safe.
The sexual ratings (one per image)
Sexual implications, risqué acts, and minor nudity.
- Breasts/buttcheeks/crotches any more than half uncovered on species that normally cover up
- Sexualized scenarios (adults in diapers, transgender transformation, etc.)
- Sexualized touching of breasts/buttcheeks
- Sexually emphasized body areas, such as "presenting" poses, "feet worship", prominent crotch bulges, or obviously-hard nipples
- Pubic hair (note that use as a censor is questionable)
- Sexual innuendo (including visual, such as crotch sub sandwich or penis shapes)
- Kissing with spit coming out or clear tongue use
- References to genitalia/sex/sex acts
Not-quite-sex, intense acts, and nudity.
- Nipples on breasts
- Sexually-emphasized gross scenarios, such as:
- Being in a throat, stomach, or intestines
- Morbid obesity
- Bodily waste being excreted, held in clothing, or sensually interacted with
- Feet licking
- Barely-concealed or clothing-outlined genitals (cameltoe etc., more than a bulge)
- Moderately-detailed (an outline and inner solid shape only) sheaths or anuses (like a star/dot in a circle or a crescent/line/dot in a bump)
- Simple (only an outline or solid shape) sheaths or anuses (like a star, circle, or bump) are as normal (suggestive if sexualized, safe otherwise)
- For these purposes, sharp contrast counts as forming lines/shapes
- Sexualized touching of the following areas:
- Between buttcheeks or around the anus
- Sex toys
- Would-be sex or ejaculation with stand-ins for genitals/anuses (such as sub sandwiches or horns)
- Implicit insertions (clearly going up a hole, but not visible and not done for them to get off, such as enemas or a comedic shove)
- Descriptions of sex
Sex, sex fluids, and major nudity.
- Genitals (penises, vaginas/vulvas, balls, etc.) including any detailed visuals of them
- Detailed anuses and sheaths
- Sex (genital/anal stimulation, even if not visible)
- Sexual bodily fluids (cum, precum, or vaginal fluids)
- Extremely detailed descriptions of sex
The dark ratings (one per image)
Dark, but not nightmare-inducing.
- Grimdark implications
- Non-serious grimdark situations (dark comedy)
- Fresh amputation
- Grave injury
- Murderous insanity
Dark to the point of nightmares/PTSD.
- Violent/painful death
- Horrific sights (such as extreme gore or eldritch abominations)
- Rape (not surprise sex or rape-play, traumatic to receiving party)
- Other traumatic situations (such as torture or extreme captivity)
The gross rating
- Body horror
- Extreme filth
- Detailed solid or semi-solid bodily waste, such as poop or vomit
Other important tags
You will likely be banned for repeatedly not tagging these, as with ratings.
artist:artist name here— specifies the work's artist
- artist needed (21201)— when the artist is unknown
- futa (33356)— a female, but with a penis; counts as its own gender for gender-based tags
- meta (13930)— stuff about stuff
- seizure warning (2625)— rapid animations that could potentially cause seizures
- text (32379)— when the main point is in text
These tags apply for any sexual or romantic acts as well as relationships, and no two are mutually exclusive. Note that female by default does not include futa.
You likely won't be banned for forgetting these tags, but they are still important.
