How posting works
Selby never posts to a marketplace on your behalf. Facebook Marketplace, OfferUp, Craigslist, Nextdoor and the rest have no public listing API and ban automated posting, and eBay’s requires a seller integration Selby doesn’t ship yet. Selby writes the listing once, tailors it per marketplace, copies it and opens each posting page: one paste each, and your accounts stay in good standing.
