Yeah it does smell funny, why would someone buy a lens like that and remove some elements and then return it? I also like the part where the seller states all the elements were removed except the front and then says he has no idea if anything else was removed internally. Did or did he not open up the lens and check what was missing?
Notice how it’s a “Canadian” who’s to blame for the first problem and then a guy from “Asia” (No need to specify a country, just lump them all together) who did not pay for the missing element lens. It’s always easier to blame someone far from home, it makes a better sob story. There must be a lot of heathens using eBay in those places.
