you must do a lot of dumb and shady shit to get hacked like that. i have never been hacked and my inventory in cs go was worth over 2k at one time. and like i said make it optional for those who want it and if you dont want it dont hold trades and market shit, just make it so they can't use steam support and have a big message telling them that. because i'd be happy with not using steam support just to not use the mobile auth, like i said in the post it seems like you didn't read.
