Child Safety Standards

Our position

Stamp has zero tolerance for child sexual abuse, exploitation, grooming, or any content that sexualises a person under the age of 18. The presence of such material on Stamp is a criminal matter and is treated as such.

Stamp is an 18+ adult-only service. The minimum age to create an account is 18. This is the strongest single barrier we operate against any form of child harm on the platform: minors should not be present.

What we prevent

• Production, possession, distribution, or solicitation of child sexual abuse material (CSAM).
• Grooming, sexual solicitation, or any sexualised contact with anyone under 18.
• Sexual extortion, "sextortion", or any coerced sexual content involving a minor.
• Sharing of non-consensual intimate imagery of any person, with elevated severity where the subject is or appears to be under 18.
• Use of Stamp to plan offline contact for the purpose of sexual abuse or exploitation of a minor.
• Promotion, glorification, or normalisation of child sexual abuse in any form, including via fiction, imagery, or text.

How we enforce it

• Age gate at signup. Every new user must confirm they are 18 or over. Accounts where we have reasonable grounds to believe the user is under 18 are suspended pending verification, and terminated if verification cannot be provided.
• Server-side abuse controls. Per-account rate limits, mandatory email verification before any content upload, automated image moderation on all image uploads via Sightengine including a CSAM-detection signal.
• Human review of every report. No automated removal of borderline content, but suspected CSAM is removed on receipt without waiting for human triage and preserved for evidential purposes where lawful.
• Permanent account termination on first finding of CSAM or grooming. No warning, no appeal beyond a single review by a person other than the original decision-maker.
• Cross-platform reporting. We report suspected offenders to the relevant authorities (see below), not only to ourselves.

How to report

In-app: long-press any post, message, or profile and choose "Report". Select "Child safety / CSAE" as the category. Provide any context you can.

By email: safety@stamp.foundation. Include the reported user's @handle, a description of the content, the URL or message ID if you have it, and screenshots if safe to share.

You do not need a Stamp account to report. Parents, guardians, teachers, social workers, or any concerned third party may report on behalf of a child.

If you believe a child is in immediate danger, contact the police on 999 (UK) or your local emergency number first, then us.

How we respond

• Acknowledgement within four hours for every CSAE report received.
• Action within 24 hours of receipt for suspected CSAM; faster where the reported material is clearly illegal.
• Account termination, content removal, and preservation of the material for evidential purposes where lawful to do so.
• Report to authorities as set out in the section below.
• No counter-notice to the offender for clearly illegal CSAM; the account is terminated without an appeals route.

Reporting to authorities

For confirmed or strongly-suspected CSAM, Stamp reports to:

• The Internet Watch Foundation (IWF), our UK hotline for image content.
• The National Crime Agency CEOP Command for cases involving online grooming, sexual extortion, or contact offences.
• The National Center for Missing & Exploited Children (NCMEC) CyberTipline where the case has a US nexus.
• UK police, on receipt of a formal request or where life is at immediate risk.

Stamp will preserve content and account metadata in response to a valid legal request and may share information with law enforcement under lawful process. We never voluntarily share user data outside this framework.

Legal framework we operate within

• UK Online Safety Act 2023, especially the illegal-content duties (s.9, s.10) and the protection of children duties (s.11, s.12).
• Protection of Children Act 1978 (England & Wales), criminalising the making, distribution, and possession of indecent images of children.
• Criminal Justice and Immigration Act 2008, prohibited images.
• Sexual Offences Act 2003, including communication and grooming offences.
• UK GDPR + Data Protection Act 2018, governing how we handle evidence and personal data during a CSAE investigation.

Our team and training

Stamp is currently operated by a sole director. Until our team grows beyond one person, the director is personally the designated point of contact for CSAE matters and is responsible for handling all reports.

The director has reviewed and committed to the standards set out by the Tech Coalition's Project Lantern, the IWF's reporting guidance, and the NCMEC CyberTipline reporting workflow. As Stamp grows, all new staff with content-moderation responsibilities will be trained on these standards before being given access to user content.
