-Also untrace, luck looking good boys: https://backpack.tf/profiles/76561198026659536#!/compare/1533859200/1533945600 https://backpack.tf/profiles/76561198136053973#!/compare/1533772800/1533945600

-This last one is SUPER complicated, bear with me. On the surface it looks like it sold for 28 keys, but 11 of them don't match, bringing that down to 17: https://backpack.tf/profiles/76561198136053973#!/compare/1534118400/1534291200 https://backpack.tf/profiles/76561198023218196#!/compare/1534204800/1534291200 . Here is a list of the non-matching keys: https://backpack.tf/item/2158307632 https://backpack.tf/item/4003285833 https://backpack.tf/item/4088992576 https://backpack.tf/item/4164660849 https://backpack.tf/item/7030269538 https://backpack.tf/item/5966052835 https://backpack.tf/item/4494719785 https://backpack.tf/item/6832025110 https://backpack.tf/item/6845977219 https://backpack.tf/item/6870766777 https://backpack.tf/item/6260454400

So the reason the keys with the other bots matches, is because you can see items obtained in the seller's link from trading with the bots the keys match with. The rest of the keys are all over the place and the nature of this compare just isn't worth including; this is good enough.
