Today, I'm going to show you how you can easily find out if someone could be using a bot and if not at least how much they paid for a hat.
So it all started yesterday when I reported some unusuals hats selling for less than $1, so immediately a few people made the comment they were probably bought by auto-buying bots.
So I decided, ok let's find out who bought this hat:
Immediately, I set up a steam alert to send me a message when the item would be put up for trade:
I filled the fields: "Unusual, Noble Amassment of Hats, Hellfire"
And I waited... until my steam alert sent me this message:
Trade.tf Alert Bot #: level 73 Unusual Noble Amassment of Hats (Hellfire)
Yeah, same level, same effect, same hat put up for sale one day after being bought, so there's a good chance it's the same.
However this person is not the auto-buyer, to find the auto-buyer we need to check one more thing: let's see if the item was relisted on steam market:
And bingo! "6ect666" relisted it 4 hours ago on steam market for $200, so that's $199 profit!
That last guy is probably the bot.
As a final tip, searching for closed trades on trade.tf can give you a lot of insight on prices (esp. unusuals) and if there's enough interest, I might do a little write up about it one day.
