    How it works

    1. 1

      Pick the marketplace

      Each platform bans different things. Mercari bans trades, Poshmark doesn't. Bol.com caps titles at 70 characters, Amazon at 200.

    2. 2

      Paste your title and description

      Preflagged checks them as you type against that platform's published rules and a list of trademarked words that catch sellers out.

    3. 3

      Fix what's marked

      Every finding says why it's risky, what to write instead, and links the policy or court record it comes from.

    Questions

    Is a clean result a guarantee my listing won't be flagged?

    No. Marketplaces publish what they ban, but not how strictly they enforce it or the activity limits that trigger reviews. Preflagged catches what the written rules and known trademark cases make predictable. A clean result lowers your risk; it can't remove it.

    Where do the rules come from?

    From each marketplace's own policy pages where they're public, and from seller-guide summaries where the official page needs a seller login. Every finding links its source and marks summaries as such. Trademark warnings link the registration, court case or brand statement behind them.

    Do you store the listings I paste?

    No. The checks run in your browser and the text is never sent anywhere. The only things we store are reports you choose to send, with emails, links and phone numbers removed.

    What happens when a marketplace changes its rules?

    Every policy page behind the checks is re-read each week. When a rule changes, the matching check is updated and the change is dated.

    Is this legal advice?

    No. Preflagged is a checking tool, not a law firm. If you've received a legal notice or a lawsuit, talk to a trademark lawyer.

    Are you connected to any marketplace?

    No. Preflagged is independent and isn't affiliated with or endorsed by any marketplace or brand named on this site.
