What happened? Description:

I was using steam discussion: trade, named Open trade. Then he comment me to add him, so i did it. Then he suggest me to using discord, so i did it. then he suggests that we are making trade at bitskins, so i did it. It's my first time to do that in bitskins, and so says to him. but first, he said I need to trade my items first, so he can make best prize for him. I don't know what's happening, so did as what he says. then my items are gone, he says I need to click Help-Contact us button. But He says everything I type needs to screen share, even my steam code and recovery code, using discord. So I did what he says, and said again, go to my email message and delete 3 messages:Your steam gaurd has disabled, Your email has changed, Your passworld has changed. I didn't do it, just I said It's done to him. then He goes offline, take all my tf2 stuff and 3 Dota2 weather effects(Geniune) , and my accounts. Luckily, I have a way to get my account back. Everything is OK but My items. and Now I have to type pin code to disable familty view using unknown email. and I talk with him later but he said he doesn't remember me, even I show him evidence. I was going to report through steam, but It's not worth the weight. So Now I have to do is reporting him by not steam but steamrep. This is my only hope. You are better than Volvo, are't you?
