Did you farm tf2 items by several 'idle' accounts to further trade in the past?
The main reason I am upset is that if I can't make future purchases, then I basically can not buy any DLC for any games I already own.
Making a new account is a huge hassle. I'd have to
-Rebuy games I already own if I want to buy DLC. Including $60 for Black Ops2 if I want to play any of the upcoming DLC maps
-Lose any progress that may apply from games that bind their account to steam account (like CoD unlocks)
-Lose all friends on my friend list and have to rebuild it
-Keep track of which games are on which account and constantly switch back and forth
-Lose my entire steam inventory, including TF2 items and any of those one-time exclusive items that I have
The account action I received is usually reserved for chargebacks and credit card fraud so I am completely confused why they did that to my account out of nowhere. I also haven't even traded in several months so I doubt I received some game that turned out to be fraudulently purchased, plus none of my games are missing from what I can tell. I guess all I can do is wait, but my previous tickets were not handled very well for minor issues compared to this. Usually they would post a non-related response and close my ticket like they didn't even read it.
I've got a friend, who was farming tf2 items for a quite long time and suddenly he got banned just because of this ~3 months ago.
