Account security is your responsibility.

Even if someone "hacked" your account (hacked is false, hijacked more), the ban would still be correct and permanent.

Accounts get banned, not people using them so you are free to create a new account and start fresh.

But protect your account better than with this account.

引用自 StellarWanderer：

меня забанили без какой-либо причины 2130 дней назад, после того как мой аккаунт взломали, написали мол аунтификатор использовался в игре с софтом, но и почту у меня украли в тот самый разгар, через 2 недели я востановил почту, а еще через пару месяцев и аккаунт, но перестал играть. Хотелось бы очень очень сильно, чтобы меня и мою ситуацию поняли и разблокировали мне аккаунт, так как он мне очень важен.

remember this thread - https://psteamcommunity.yuanyoumao.com/discussions/forum/9/1753525962483406311/ going from i didn't cheat to i been 'hacked". Answer is still the same from last time. Irrelevant who used the account, your 2130 day old vacban is permanent (already been checked and rechecked before you made your first thread)

Can I appeal my VAC ban?
No. VAC bans cannot be appealed. If a VAC ban is issued incorrectly it will be automatically removed after investigation, but Steam Support does not manually remove VAC bans applied to accounts for any reason.

I was not using my account when it was VAC banned. Can the ban be removed?
No. Any bans added to an account will remain regardless of who was using the account at the time the infraction occurred. Ultimately, the use and security of your Steam account are your responsibility.

While we understand this can be frustrating, we must maintain a zero tolerance policy for cheating to foster a fair game that all players will enjoy.
