This is nothing new. Those are automated bots spamming everyone. Report them (on Steam), block them, remove them, move on.

And this guy calling it "glitched", which isn't true.

You can still do it. It works on any weapon, just apply the killstreak, remove it and then make a nice backstory about how rare it is.

There's a limit for inventory calls which is 2500 items. It was added only recently.

It's not really important, just wanted to point out that those trades are indeed recorded just like any other.

Not true.

How am i supposed to know? I can't see my trades that i haven't gotten anything for, I have been owing my brother alot of stuff and i can't see those trades in my trade history, also a loooooooooooong time ago i got scammed a couple of times with PayPal and them trades can't be seen in my trade history either, maybe it has something to do with your security settings or something like that. Otherwise it's just edited by some program like Paint.net or other.

I can see every single trade of mine. All of them. Does not matter, who gives items. All of them are there. And I'm talking about: https://steamhost.cn/steamcommunity_com/my/inventoryhistory/ (just in case).

However, sometimes (especially during weekends), the trade history will NOT load correctly and it will display incomplete data.

And last thing, trade history was added AFTER trading was added into TF2, so it does not include very, very old trades.
