What they did
He uses Grok Bot to sell on Facebook Marketplace with strict rules. Titles follow one fixed template. It researches a price and explains why. It never publishes without a separate yes from him. The price goes only in the price field, it never shares his home address (it suggests a public meetup spot), it answers only routine questions about the item, and it never negotiates or agrees to pickup times.
How it went
Marketplace listings drafted and priced to your rules, with you keeping control of deals.
Worth knowing
- One person's X post. Marketplace sometimes restricts automated activity; keep the bot drafting while you post and message.
