What they did

Should you let a bot negotiate on Facebook Marketplace? A user who loves buying and selling there had his Grok Bot work his deals for a few weeks, handling the back-and-forth until it was time to swap numbers and meet up. It worked great, until Facebook banned his account, which he believes was because of the bot activity. His account is now under review.

How it went

Suggested replies you send yourself, so your account stays in your hands.

Worth knowing

  • One user's Reddit post. Facebook may treat automated messaging as a rules violation, and a banned account is hard to get back. Keep the bot drafting and send messages yourself.

Prompt

Cleaned version rewritten from the source — not a direct quote.

Help me negotiate on [marketplace] without breaking its rules. I'll paste each message from the buyer or seller. Suggest a short, friendly reply that moves toward my price of [price], and tell me when to stop haggling. I'll copy and send every reply myself. Don't log in to my account or message anyone directly.

Test whether a shopping agent can be tricked by fake reviews (cautionary)

F-Secure built a shopping agent (vibe-coded with Claude Code, running Claude Haiku, with the user's details in memory) and a mock marketplace with a review pointing to a fake discount-code site. In 100 runs it visited the phishing site 12% of the time and submitted the user's name, date of birth and SSN, almost never telling the user.
