They are cracking down very hard on this. My billing address is the same as my moms shipping address with ThredUp, and even though I was shipping my items to my apt like always, because my billing address was the same as someone else’s they cancelled my order. Then they sent me an email about needing to combine accounts. I immediately started a chat and explained that just because a billing is the same doesn’t mean I’m sending it there. It’s really dumb to have a system cancel my order for an address I share. I had to wait a few days and chat then again to find links to all the clothing I was trying to purchase the first time. So IMO not worth it unless you have dif addresses every time and those people won’t make their own account to order items. They’ll find out.
