HWID

I know it is not really related to the subject, but I was really wondering. 

Why people ask for a HWID reset? does CS:GO use it to track cheaters like other games?

Hardware ID is like a fingerprint of your PC - once you change any part, the ID also changes. People request a HWID reset after the client dismatches the new ID with the old one, happens while changing pc parts. Often scenario is that people also try to re-sell the account, which violates our Terms of Service so they get banned.
