Your friend(not you or anyone else) should create a support ticket if you want that fixed.

Also you've said some things that shouldn't have been admitted to. Be more careful with admitting to breaking the Steam Terms of Service, like the sharing of accounts.

Anyway, good luck to your friend.

Apologies I'm new to discord he wanted me to join steam. The problem is that his PC broke down and he has a black out. So he ask me if I could ask. It wasn't my intention

That was my mistake. Can you give me some advice I can tell him to do to get that resolved?

Steam main window(if he can log in)
Menu bar
Help>Steam Support

https://psteamhelp.yuanyoumao.com/en/
That page is also reachable through your browser login.

Click on Steam Community
Click on "I need help with something not listed here."

Scroll to the bottom of the page.
Click on "Contact Steam Support"

Then fill in the text box, pray to Gaben and then click Send.

Its probably best to not reveal any specific names, passwords, etc. Maybe have a proof of a game purchase(receipt, key, etc, but they'll let your friend know what he needs to provide).

And as for the lock itself, when they use the expiration year of 2038 it means its really forever. When 2038 comes around they'll bump it to the next 'forever' expiration date.

Good luck.

Thank you very much. Happy holidays

2038 is a placeholder for "permanent". If it's a permanent ban, and for what I guess was about sharing accounts, it's most likely never going to be removed.
