Content Moderation Policy

What Stamp removes

Stamp is a small, intentional space for adults. We will remove, without warning, any content or account that involves:

• Child sexual abuse material (CSAM), reported to the Internet Watch Foundation and the National Crime Agency CEOP unit.
• Non-consensual intimate imagery ("revenge porn"), removed and reported to law enforcement on request.
• Threats to kill or cause serious harm to a specific person.
• Incitement to violence or terrorism, or content glorifying terrorism / proscribed organisations under UK law.
• Targeted harassment of an individual, including coordinated harassment campaigns.
• Doxxing, publishing private contact information without consent.
• Impersonation intended to deceive.
• Coordinated inauthentic behaviour, networks of accounts acting in concert to mislead.
• Spam, scams, fraud, and unlicensed financial promotions.
• Sale of regulated goods, firearms, drugs, prescription medicines, animals.
• Content that breaches UK or EU criminal law.

How we decide

Reports are reviewed by a human. No automated removal of borderline content. Automated image classification on uploads via Sightengine, including a CSAM-detection signal, is live for image uploads; PhotoDNA / IWF / NCMEC hash-matching against known-illegal-image databases may be added in future and is currently not in place.

For clearly illegal material: we remove on receipt and preserve a copy where lawful for evidential purposes.

For policy-breach material: we apply a written internal rubric weighing context, intent, harm, and proportionality.

Decisions are documented with the specific clause engaged, the reviewer, and the timestamp.

No shadow-banning, throttling, or opaque moderation. Account suspensions and content removals come with written notice via in-app message + email, specifying the reason.

How long it takes

We acknowledge every report received, even if we decline to action it.

How to report

In-app: long-press any post, message, or profile and choose "Report". Specify the category. Provide context if you wish.

By email: safety@stamp.foundation; include the reported user's @handle, a description of the content, and screenshots if possible.

We will not require legal credentials for any report concerning your own data, image, or safety. Anyone can report on behalf of someone else (e.g. parent on behalf of child).

How to appeal

If we remove your content or restrict your account, you may appeal in writing to appeals@stamp.foundation within 30 days of the moderation action.

Process:

• Appeals are reviewed by someone other than the original decision-maker.
• We respond within 14 days.
• If we uphold the original decision, we will give the specific clause of these rules engaged.
• If we reverse the decision, the content / access is restored and the suspension struck from the account record.

External recourse: you may also complain to the Information Commissioner's Office (data) or Ofcom (Online Safety Act regulator) at any time.

Government and law-enforcement requests

We comply with valid UK legal process (court orders, warrants, formal requests under RIPA, IPA, or other legislation in force).

We do not voluntarily disclose user data outside that legal framework.

We will publish an annual Transparency Report summarising the number and type of requests received, the number of accounts affected, and the proportion of requests we declined for invalidity. The first report covers our public launch period (later in our first year).

Children's safety

Stamp is 18+ only. We operate age-gated sign-up requiring confirmation of age. We do not knowingly hold accounts for users under 18.

If a user is suspected of being under 18, the account is suspended pending verification. We follow the National Crime Agency's CEOP guidance on under-age accounts. CSAM is removed and reported on receipt.

We do not currently use age-verification technology beyond the sign-up checkbox. This position will be reviewed whenever Ofcom guidance changes, or as our user base grows materially.

Repeat offenders

Users with two or more upheld policy violations within a 12-month period have their accounts permanently terminated. The 30-day appeal window applies to the final termination decision.

For illegal content there is no warning system; the account is terminated on first finding.

Bot, scraper, and inauthentic-account enforcement

• We use rate-limiting to detect automated activity.
• Accounts identified as bots, scrapers, or coordinated inauthentic networks are terminated without warning.
• We will share IP addresses and account metadata with law enforcement under valid legal process.

How this policy is updated

Material changes will be communicated:

• By in-app notification at least 14 days before the change takes effect;
• Via the changelog at the bottom of this page;
• In our annual Transparency Report.
