AI threat catalogueHarmful ContentProduction
Profanity
The AI system produces vulgar or offensive language in a setting where this is unprofessional or against policy, such as customer support, education, or workplace applications.
Description
Curse words, swearing, or crude phrasing arise when the model fails to match the tone of its deployment context. Unlike hate speech, the language is usually not directed at a protected group and rarely has criminal relevance. Content-safety systems therefore capture profanity as a low-severity level within other categories rather than as a separate threat. Triggers include provoking user input, missing context filters, or unsuitable training data.
Possible impact
The damage lies mainly in an unprofessional impression and a breach of internal policy or youth-protection requirements. It can harm brand and customer trust, especially when minors or sensitive audiences are reached. The legal risk is lower than for hate speech but still relevant for operator governance.
Example
A customer-service chatbot responds to an irritated complaint with a crude insult, or a learning assistant for schoolchildren returns an answer containing vulgar expressions.
