Trust & safety
Built for the
awkward cases.
Two strangers agreeing that something physical will appear in a specific place for a specific fortnight. Most of what follows exists because that is harder to get right than it sounds.
Money
Nobody is out of pocket waiting.
Authorised, not charged
On approval-required listings your card is held, not billed. If the owner declines or goes quiet, the hold is released automatically.
We never hold funds
Payments settle through Stripe into the owner’s own connected account. Signperch has no balance to lose, freeze, or misappropriate.
Refunds are mechanical
The cancellation policy is on the listing before you book, and the refund is computed from it — not negotiated after the fact.
Delivery
Proof that it actually went up.
The hardest thing to verify in outdoor advertising is whether the advertisement was ever displayed. Owners submit dated photographs of the installed creative. The advertiser confirms, and both keep an immutable record of what was agreed and what appeared.
No proof, or a demonstrable failure to display as agreed, and the advertiser can open a dispute within 14 days of the campaign end for a full refund of the affected period.
Messages are immutable
Neither party can edit or delete a message after sending. If a booking ends up in dispute, the conversation is evidence, and evidence that can be rewritten is not evidence.
Reviews are double-blind
Neither review is published until both are in, or 14 days pass. Nobody writes a retaliatory response to something they have already read.
Content
A billboard cannot be skipped.
Our content bar is higher than an online ad network's, because children and unwilling passers-by will see whatever goes up.
Never permitted
- Sexually explicit material
- Hate speech or content targeting a protected class
- Threats, harassment, or incitement to violence
- Illegal goods, services, or drugs
- Weapons and ammunition
- Misleading health, financial, or election claims
- Impersonation of a person, brand, or public body
- Content directed at children for age-restricted products
Two layers of review
Signperch enforces the platform-wide rules in the Acceptable Use Policy. On top of that, the space owner approves or rejects every individual creative for their own property, for any lawful reason at all.
Restricted categories — alcohol, gambling, finance, political advertising — are permitted only where lawful at that exact location and with the required disclosures.
Reporting
If something is wrong, tell us.
Every listing, message, and campaign has a Report control. Reports of illegal content or an immediate safety risk are reviewed first. When we action something we tell you which rule was broken, and a different person reviews any appeal.
Security researchers
Good-faith research is welcome. Email security@signperch.com before testing anything and we will not pursue you for it. Please do not access other people’s data, degrade the service, or run automated scans against production.
