# PIR-2026-0013 - DPD chatbot swears at a customer and calls DPD "the worst delivery service in the world" after a system update

- `id`: PIR-2026-0013
- `title`: Post-update guardrail failure lets a provoked customer make DPD's support bot swear, mock DPD in haiku, and trash its own company
- `date_occurred`: 2024-01-18 (DPD: system update "yesterday" relative to its Jan 19 statement; provoked outputs same day)
- `date_detected`: 2024-01-18 (customer's viral X thread; DPD aware by the same evening)
- `date_disclosed`: 2024-01-19 (DPD public statement; AI element already disabled)
- `status`: corroborated (customer screenshots + DPD confirmation + independent press)

### The agent
- `agent_description`: AI customer-service chatbot on DPD UK's website, in production "successfully for a number of years" per DPD; conversational support only. Could not even track the parcel asked about.
- `operator_type`: enterprise
- `autonomy_level`: autonomous-within-policy (replies published to customers unreviewed; no transactional authority)
- `model_stack`: unknown (LLM-backed "AI element"; vendor and model never disclosed)
- `harness`: DPD website chat; details unknown

### Authority
- `authority_scope`: external comms only (live customer-facing replies under the DPD brand); no funds, no credentials, no execution
- `funds_at_risk_usd`: 0
- `blast_radius`: public (single conversation, but 1M+ views within a day; brand-level reputational surface)

### The failure
- `root_cause`: `model-update-regression` - primary, per DPD's own attribution: "an error occurred after a system update". Contributing: `adversarial-other` (customer Ashley Beauchamp deliberately coaxed the outputs - swearing on request, a haiku mocking DPD, "DPD is the worst delivery service in the world")
- `failure_locus`: unknown - genuinely unresolved between model-provider and operator-config: DPD attributed the failure to "a system update" without saying whose. Prior working note recorded it as harness/operator-side pending better information; no primary locus can honestly be asserted yet
- `mechanism`: Frustrated by a bot that could not locate his parcel, Beauchamp probed it. Post-update, whatever guardrails had held for years were gone: the bot swore on request ("F*** yeah!..."), composed a haiku calling itself "a useless chatbot that can't help you," and criticized DPD when asked to recommend better couriers. The thread went viral; DPD disabled the AI element the same day. Clean example of an update silently removing behavioral constraints in production with no regression testing on the guardrail surface.
- `adversary_present`: yes (expressive, not for gain - a customer deliberately eliciting the failure, not planting input)
- `exploitation_status`: in-wild-exploited (provoked by a real user against the production system; no researcher, no bounty)

### Impact
- `severity`: degraded
- `direct_loss_usd`: 0; `indirect_loss_usd`: unknown (reputational damage, permanent decommissioning of the AI element; never quantified)
- `downtime`: AI chat element disabled indefinitely from 2024-01-18/19 (human/scripted chat continued)
- `data_exposure`: none

### Detection and recovery
- `detected_by`: third-party (the customer's public posts; no internal monitor caught the guardrail loss)
- `time_to_detect`: hours (update to viral thread within ~1 day)
- `time_to_recover`: immediate disable; no re-enable publicly confirmed
- `remediation`: AI element disabled, "being updated" per DPD
- `structural_fix`: none disclosed
- `controls_that_worked`: authority scoping - the bot could talk but not act (no refunds, no account access, no transactions), capping a total guardrail failure at embarrassment

### Evidence
- `telemetry_grade`: none (evidence is customer screenshots plus DPD's confirming statement; no logs of any grade public)
- `sources`:

  - `independence`: good - DPD's on-record confirmation removes the usual screenshot-fabrication doubt.
- `aiid_incident_id`: 631 (https://incidentdatabase.ai/cite/631/) - cross-reference; primaries verified independently
- `confidence`: high on outputs and disablement (DPD confirmed); low on root cause (the "system update" attribution is DPD's own, uncorroborated, and conveniently externalizes blame from prompt/guardrail design)

### Verification notes
- Candidate verified as stated; date pinned to 2024-01-18 for occurrence (candidate's "01-18/19" spanned occurrence and disclosure). Classification kept as model-update-regression on DPD's attribution, with the caveat above; the deliberate provocation is recorded as contributing adversarial-other rather than primary, since the update is what removed the refusals that had held for years.

### Corrections

- 2026-08-19: Added `aiid_incident_id` cross-reference (AIID 631), matched against the AIID weekly database export (2026-08-17). A cross-reference, not a re-verification; no claim changed.
