Using last month.

Sale 1:

Sold to a bot for 3 keys + 11 ref?

Seller: https://backpack.tf/profiles/76561198003824831#!/compare/1542672000/1542758400

Buyer: https://backpack.tf/profiles/76561198311725787#!/compare/1542672000/1542758400

Keys match, I don’t doubt that bot.tf is incorrect here.

Untraceable

I’m certain the 2nd link isn’t the buyer of the 1st link’s sale. Looks like there was another person that didn’t pop up in the history.

https://i.imgur.com/lqpc2IX.png - B/O of 3 keys + 28 ref (~3.5 keys)

May be better to use on the results, as we already have 2 sales at 3.5 here. This would most likely end up being 3.5 as well if used here.
