There have actually been a few bypasses at certain points, there was a .bat file that deleted certain files that allowed users to trade again for a short amount of time. You may very well be right, and valve may have patched all of the methods, but I hope not!
Hi, I've been vac banned on CSGO on my storage account, meaning that i've just lost a lot of money in skins. Ill pay $15 for any way of bypassing the trade ban.
