Cs go VAC BAN question :)

Hello all :)
I would like to know how the cs go bans work, so i can buy the hack from here and start cheating,

Now: I want to hack on a SMURF/Second account But if the smurf gets a VAC BAN, will that affect my main account in any way ?
Are there some things i have to do to prevent this from happening ?

I want my main account to be clean for 100% sure please let me know

The only way your main will be banned is if both accounts share the same phone number for the mobile authenticator if it is used..

No, but do not link the same phone number as your main account

If you don't want to get banned on your main account, you shouldn't link your infromation or, and your mobile phone number to your second account
