Rules
More detail: Post one listing in many buy and sell groups.
- One listing goes to at most 20 groups. At most 3 listings are sent a day.
- The same listing never goes to the same group twice within 24 hours.
- Profile only. Facebook keeps Pages out of Marketplace, so a Page cannot list.
- The listing goes first, then the regular post goes to the other groups in the list.
- Without a listing, buy and sell groups are left out of the run and the result explains why. It is not a block.
- Facebook reviews a new listing before it shows (usually a few minutes), so do not send it again.
For AI agents: every docs page has a Markdown copy (add .md to the path), the whole section is indexed in /docs/llms.txt and /docs.json, and the MCP server is described on /docs/mcp/.
