Second Account

Hi, i have my main account where mi save is legit and i have more than 1000 hours played. But one friend gift me a new key for the game, and i want to create a new user in steam and use a save file from here. Dont care if i am banned with this new account, but i dont want any trouble with my main. Is there any risk? Is there any way to relate both accounts? Thanks.

Nope. There should not be any risk.

No, each account is different, you have to commit an offence on the specific account, and only that account will be banned.

In short : No. There is no risk.

One friend of mine got banned on both his account because they were on the same computer, he got a eac ban for cheating on one account and hacking for the other, while he has one account with only a non-legit savefile (the one he was supposed to be hacking) and one legit account without any game modification (the one he was supposed to be cheating but he was not lol), be careful, maybe he was just unlucky

Was the savefile the only thing he changed? Did he change any of the pak files?
