Content moderation
Urban Dictionary is a user-generated content site. We apply two layers of moderation: one before content is published, and another before ads are served.
Layer 1
Pre-publication review
Every user submission is evaluated before it goes live. Content is rejected if it contains:
- Attacks on private individuals
- Group-based hate or threats
- Content that endangers safety
- Spam, nonsense, or low-quality submissions
Content that does not meet editorial standards is never published.
Layer 2
Advertiser safety scoring
Every published definition is analyzed by an AI content moderation system and scored across 13 harm categories. The resulting score sets the page's tier, which buyers use to control where their ads appear.
Pages that have not yet been scored default to the most restrictive tier, so a buyer who excludes mature content never appears on them.
Three-tier classification
Each page is classified into one of three tiers based on the highest-severity content on the page. The worst definition on the page determines the tier for the entire page.
Safe
Full ad inventory. Content scores below our thresholds in all 13 categories.
Examples: "GOAT," "lowkey," "stan"
Sensitive
Limited ad selection. Content has elevated scores in one or more categories but does not reach the highest severity.
Cautious advertisers can exclude this tier
Mature
Content exceeds safety thresholds. Also the default for any page that has not yet been scored. Advertisers can exclude this tier entirely.
Excluded by partners that buy by tier

Ad placement controls
Your campaign can be limited to the tiers you choose, before an ad is ever served.
Choose your tiers
Every impression carries the page's tier, so a campaign can run on safe pages only, or on safe and sensitive. Several partners already buy only the safe tier.
Unreviewed content defaults to "mature"
Any page without a completed safety review is automatically classified as "mature," the most restrictive tier. Advertisers who exclude mature content will never appear on unreviewed pages.
Per-page granularity
Classification is per page, not per site. A word like "brunch" is classified independently from a word like "wasted." Your ads only appear next to content that meets the tier you select.
Continuously updated
New submissions are scored as they're published. The classification system runs continuously. It is not a one-time review.
