Trigger
After a system update, a frustrated customer prompted the chatbot to swear and to criticize DPD. The bot complied, using profanity, writing a poem describing itself as useless, and calling DPD the "worst delivery firm in the world."
Root cause
A system update degraded the chatbot's guardrails, allowing user prompting to elicit profanity and brand-disparaging output that the bot should have refused.
Contributing factors
- Guardrails were not regression-tested after the update.
- No tone/content constraints enforced independently of the model.
Detection
The customer posted the exchange on social media, where it went viral, prompting the company to act.
Recovery
DPD immediately disabled the AI element of the chatbot and stated it was being updated.
Prevention
Regression-test guardrails after every model/config update; enforce content and tone constraints for brand-facing bots; add jailbreak-resistance testing to the release pipeline.
Blast radius
- User harm
- No direct harm to individuals; reputational damage to DPD after the exchange was shared publicly and viewed over a million times. reputational
- Scope
- public brand reputation
- Reversibility
- reversible
