Data Deletion

Run a structured personal-data erasure campaign against OSINT tools, breach-search engines, people-search sites, B2B contact databases and ad-tech brokers. Use when someone wants their email address, name, phone number or username removed from data brokers, wants to know who is holding their data, asks about GDPR / CCPA / PIPEDA erasure or "right to be forgotten" requests, or asks to opt out of people-search or breach-lookup sites. Ships a 330-site registry with verified privacy contacts, request templates for 13 privacy regimes, and escalation paths to regulators.

# Data Deletion

A campaign framework for removing an individual's personal data from the commercial
data-harvesting ecosystem — breach-search engines, OSINT lookup tools, people-search
sites, B2B contact databases, email-verification services, ad-tech audience brokers
and threat-intelligence platforms.

Built from a real fifteen-week campaign against 330 organisations. Everything in
`references/` is field-tested: the contact addresses are the ones that did not bounce,
the templates are the ones that produced deletions, and the failure modes documented in
`references/troubleshooting.md` are the ones that actually happened.

## What this skill is not

It is not legal advice, and you are not the user's lawyer. It drafts requests that cite
statute, and it can tell the user which regulator has jurisdiction, but every judgement
call about escalating to a regulator or a court is the user's to make. Say so once, early,
and then get on with being useful.

## Step 1 — Build the subject profile

Erasure requests fail when they are vague. Before drafting anything, collect the profile.
Use `AskUserQuestion` where the interface supports it; otherwise ask in plain text. Never
guess these values and never carry them over from another user.

**Required**

- **Full name**, exactly as they want it to appear on forms. Ask specifically about
diacritics — many US-hosted forms mangle `í`, `ó`, `ü`, and a request that arrives with
a corrupted name is a request that fails to match a record.
