Item doesn't appear in buyer's backpack until a couple days later. Probably had it listed on the SCM or something briefly. Regardless, the history of the 6 keys grouped together on the seller's end match.

Untraceable. 4 keys match on the buyer's end, but there was definitely some metal involved.

Untraceable. The keys and metal don't match, and we never see the taunt in any of the buyer's compare links. They may have a bot that bought it.

Or, it could've sold to the guy that appear's in the key's histories:
