We don’t have any problem with people selling their second-hand goods on the social media marketplace. Even though the average seller won’t be a marketing expert, you’d expect them to at least be honest. However, that’s not always the case, as you can see from this guy trying to sell a baker-style tent that was used from the mid-1800s.

That’d be impressive if it were true. They said that the tent has polyester, which was invented in 1941. Unless the polyester canvas was a later addition (no description in the ad), then we’re going to assume that something doesn’t add up here, and this guy’s pants are on fire.
