After getting scammed on Facebook Marketplace, I look at the profiles of sellers, particularly if they don’t have much in way of reviews. That seems more prudent than creepy to me. I’m not stalking anyone and I’m not looking to be their friend.
Is there a better way to do seller verification? It does seem like an information leak to me. Craigslist and eBay don’t share my identification as a potential buyer. I don’t love the marketplace being tied to a social network, but it’s what many people are using these days.
