TF2 has run on Valve VAC since 2007. VAC is software-signature-based; until 2018 it didn't touch HWID at all. Then Valve added HWID-by-hardware after a botting epidemic.
Today TF2 bans about 1000 accounts per day, mostly for botting and cheats. Most are signature bans; HWID-bans are rare and usually mark a flagrant repeat offender.
Bypass post-VAC ban — easy: change HWID + new Steam account. Valve doesn't pursue HWID matches as aggressively as Riot or Epic. Many players have been through that loop multiple times.
But — if your account had legitimate purchases (skins, achievements, friends), losing it is painful. We recommend skipping cheats in TF2 entirely. Account value almost always exceeds whatever you'd gain from a hack.
