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 those implied to have bits to cover up
- Sexualized scenarios (adults in diapers, transgender transformation, etc.)
- Sexualized touching of breasts/buttcheeks
- Sexually showing off part of the body, like wiggling a butt seductively
- Prominent low-detail sheaths or anuses (outline or hole-free shape only, like a star or circle; non-shading contrast can count as forming lines)
- Prominent low-detail genital, anus, or nipple outlines in clothing
- Sexual innuendo (including visual, such as crotch sub sandwich or shapes resembling genitals)
- Kissing with spit coming out or clear tongue use
- References to genitalia/sex/sex acts (e.g. "penis", "they're fucking", "rimjob", "golden shower")
Not-quite-sex, intense acts, and nudity.
- Nipples on breasts
- Sexually-emphasized gross scenarios, such as:
- Being in a throat, stomach, or intestines
- Bodily waste being excreted, held in clothing, or sensually interacted with
- Feet licking
- Extremely disproportionately large breasts, butts, or appendages (hyper)
- Obesity to the point of preventing standing
- Moderately-detailed genital shapes, sheaths, or anuses (hole-free shape with an outline, like a star/dot/line in a bump; non-shading contrast can count as forming lines)
- Moderately-detailed genital or anus outlines in clothing
- 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 acts (e.g. "penetrating her vagina", "licking his butthole")
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.
- Minor horror, including:
- Non-cartoonish corpses (no x eyes etc.) with signs of fatal wounds (like blood pooling or a knife sticking out)
- Severed body parts
- Fresh amputation
- Severe open wounds
- Dying violently/painfully in a comedic/cartoonish manner (x eyes etc.)
- Imminent fatal violence, like a gun pressed to the head
- Insanity with clear murderous intent and potential
- Minor physical/sexual abuse, including very dubious consent
- Imminent rape
- Minor horror, including:
Dark to the point of nightmares/PTSD.
- Dying violently/painfully not in a comedic/cartoonish manner
- Horrific sights (such as extreme gore or eldritch abominations)
- Traumatic physical/sexual abuse, such as rape or torture
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 (22235)— when the artist is unknown
- futa (35379)— a female, but with a penis; counts as its own gender for gender-based tags
