I just got a bunch of sale notifications for items i never listed, and my wallet says its pending income. I did not list these items and i want to stop this, how do i stop it and how do i figure out how my items were listed.
The items are TF2 vintage items, not alot of stuff , but the fact this has happened tells me my accounts been violated.
I use steam guard mobile auth no one should be able to get into my account.
