Acceptable Use Policy

Effective 15 September 2026. This policy forms part of the Terms of Service. Capitalised terms have the meaning given there.

Clobber is infrastructure, and you are the operator of the markets you run on it. That division only works if certain things never happen on our machines, whatever your local law permits and whatever your users want. This policy is that list. It is short on purpose, it is not negotiable, and breaching it lets us suspend or terminate immediately.

#1. Markets that are prohibited everywhere

These are prohibited in every jurisdiction, on every plan, with no exception and no licence that unlocks them. Do not create a market:

• on the death, injury, illness or physical harm of any person, or on an act of violence, terrorism, war crime or assassination;
• that creates an incentive for someone to cause the outcome, where that outcome is a crime or a serious harm;
• on the private life of an identifiable private individual: their health, their relationships, their sexuality, their finances, their criminal exposure. Public conduct by public figures in their public role is not what this covers;
• whose resolution depends on material non public information, or that is designed to compensate someone for disclosing it;
• on child sexual abuse material, human trafficking or the exploitation of minors, in any framing whatsoever;
• that exists to evade sanctions, launder proceeds, finance terrorism, or move value for a sanctioned person;
• that is designed to defraud your own users, including any market whose rules you can change after the fact, or whose resolution you control without publishing the method.

#2. Authorisation: the rule for everything else

Every other market kind is a question of whether you are allowed to run it where you run it.

2.1 The general rule. You may only operate markets you are authorised to operate, for users you are permitted to serve, in jurisdictions where doing so is lawful for you. Prediction and event markets, derivatives, betting and spot trading are licensed activities in most of the world, under regimes that differ by country and often by state or province. Identifying which apply to you, and holding them, is your responsibility and not something we assess for you.

2.2 Countries. You will declare the countries you serve and the countries you block, keep that accurate, and enforce the blocks in your own product. We do not geofence your users for you.

2.3 US persons and event contracts. You may not offer event contracts, prediction markets or other derivative products to United States persons unless you hold your own authorisation to do so, such as registration as a designated contract market or equivalent CFTC status, or a relevant no action position, and you have shown it to us during verification. Sports wagering in the United States is separately a matter of state gaming law, and the same rule applies: your licence, shown to us, or not on our machines.

2.4 Change of circumstances. If an authorisation you relied on lapses, is refused, is suspended, or stops covering what you are doing, you will tell us in writing without delay and stop the affected markets.

#3. Sanctions

Independently of anything else in this policy, and wherever you and your users are located, you may not use the Service to provide access to any person who is the target of sanctions administered by the United States, the European Union or the United Kingdom, or who is located in a comprehensively sanctioned jurisdiction. We screen customers and their beneficial owners against those lists, and a match is a hard stop.

#4. Market integrity

You will operate your markets honestly, and you will not use the Service to:

• manipulate a price or a published volume, including wash trading, spoofing, layering, painting the tape and marking the close, whether by you, by an affiliate or by a user you permit;
• fabricate liquidity or activity in order to mislead your users or a counterparty;
• trade against your own users on information they do not have, or use your administrative access to advantage a position;
• resolve a market other than by the method you published to your users before they traded.

#5. Technical use

You will not:

• attempt to access another tenant's data, probe or bypass the isolation between environments, or test the security of the Service without our prior written permission;
• exceed, or attempt to circumvent, the rate limits and request capacity of your plan, including by spreading load across accounts created for that purpose;
• interfere with the availability of the Service for others, including by deliberate flooding;
• reverse engineer, decompile or attempt to derive the source code of the Service, except where that restriction is unenforceable by law;
• resell, sublicense or provide the Service to a third party as if it were your own infrastructure, unless your agreement with us expressly allows it;
• use the Service to build a competing matching engine or exchange product;
• transmit malware, or use the Service to attack anything.

#6. Content and conduct

Market names, descriptions and metadata are published to your users and are visible to us. Do not use them to harass, threaten or defame anyone, to publish someone's private information, or to promote violence or the activities in section 1.

#7. Sandbox

Sandbox environments are free, shared and open. Do not use them with real money, real end users or production traffic, do not use them to load test without asking us first, and do not use them to work around the verification required for a production environment.

#8. How we enforce this

8.1 What we can see. We can see the markets in your environment, their metadata, and the shape of your traffic. We do not monitor the substance of your business, and nothing here makes us responsible for it.

8.2 What we do. If we believe this policy has been breached, we may restrict or halt an individual market, suspend an environment, suspend the Organization, or terminate. We will match the response to the problem and, where the breach is inadvertent and fixable, we will normally ask you to fix it first. For section 1, section 3 and anything unlawful, we act immediately and without notice.

8.3 Reports. Anyone may report a suspected breach to [email protected]. Include the market and enough detail to identify it. We investigate every report and we do not disclose the reporter to the customer.

8.4 Legal process. Where we are required to preserve or produce records, we do so as described in the Privacy Policy. We do not need a court order to enforce this policy: it is a contract, and we can act on it ourselves.

#9. Changes

We may update this policy as the law and the product change, on the notice terms in section 15 of the Terms, except where a change is required by law or by an immediate legal risk, in which case it takes effect on posting.

Questions, or a market you are not sure about: [email protected]. Asking first is always cheaper than being suspended, and we would rather have the conversation.
