Community guidelines

1Accounts

• 18 or older.
• One account per person.
• Signed-in members see your full name. Visitors who aren’t signed in see only your first name and last initial.
• Use your full legal name, including your full surname. Do not use a nickname, business name, or surname initial.

2Listing review

• Listings normally go through staff review before publication. Eligible sellers may receive Fast Track publishing, which can publish a validated listing automatically. Staff may require additional review or remove a listing that breaks the rules.
• KeystoneXchange reserves the right to reject or remove any listing at its discretion, including listings that are not specifically prohibited by these guidelines.
• We aim to review submissions within one business day, Saturday included. Review may result in approval, a request for changes, or rejection. All times are Eastern Time.
• Routine staff listing review pauses Sunday. Submissions awaiting staff review from Saturday evening or Sunday are normally reviewed Monday. Fast Track publishing may operate outside that schedule.
• Buying, selling, and messaging run every day. Only approvals pause.
• Editing a listing may send it back for review. Price changes do not.
• Fraud and safety reports are handled Sunday too.

3Language and images

• No profanity, innuendo, or suggestive language or images.
• Photograph the item, not a person wearing or holding it.

4Clothing

Outerwear and footwear only.

Photograph clothing flat, on a hanger, or on a form.

5Listings

• External links are not permitted in any listing. This rule applies to all sellers.
• Photograph the actual item yourself. No stock, catalog, AI-generated, or borrowed images.
• State condition, including damage, repairs, and missing parts.
• List a real price.
• One item or lot per listing, in the right category.
• Renew rather than delete and repost.
• Mark it sold when it sells.

6Messages

9Food and produce

• Prepared foods and canned goods require the permit your state requires. State it in the listing.
• Raw milk only where your state allows its sale, with any required permit stated in the listing, for local pickup only.

• Have the title or the legal right to sell. State title status.
• Disclose mechanical faults, salvage history, and odometer condition.
• The vehicle must be in your possession.

11Payment

• Cash on pickup for local sales. KeystoneXchange does not handle payment.
• KeystoneXchange does not send payment links or shipping labels. We send sign-in codes by email only when you request them. Never share a sign-in code with a buyer or seller.
• Report anyone who asks you to move the deal off KeystoneXchange, wire money, or send gift cards.

Nobody legitimate needs a wire transfer or a gift card.Those two requests, and anyone pushing you to keep talking somewhere else, are the signs worth reporting.

12Privacy

• Do not post anyone's personal information or photograph without permission.
• Faces are never required. Photograph the item.
• Do not publish private messages.
• Authorized staff may inspect conversations to investigate reports, harassment, fraud, and other guideline violations. Staff must record a reason, and access is logged.

13Businesses

Business owners may list items through their personal profiles. To preserve the peer-to-peer, neighborhood feel of KeystoneXchange, businesses may list only a handful of new items at a time.

14Reports and enforcement

A person reviews every report. Nothing here is decided by a machine.

1. 1RemovalThe listing comes down.
2. 2WarningA person explains what went wrong.
3. 3SuspensionAccount paused for 7 days, 30 days, or until we restore it.
4. 4PermanentAccount closed for good.

Fraud, theft, threats, and anything involving a minor skip the ladder and go straight to permanent removal.

To appeal a decision, use the Appeals page. Suspended accounts can still reach it. A different staff member than the one who made the decision reviews every appeal.

15Changes

Revised guidelines are posted here with their effective date. When these guidelines change, you’ll be asked to accept the new version before continuing to use your account.
