Sell old stuff on Facebook Marketplace without answering every message
The poster gave Grok Bot two photos of an item from his camera roll. He says it wrote the listing, looked up the dimensions and extra photos, and followed up with about 15 interested people until one bought it. His only job was sending the buyer his address.
