I am sorry Hateful, but MVPs don’t work for Blizz. I can’t see your account history. While the first penalty is usually only 24 hours, depending on severity, it can go all the way up to a full permanent ban, even for a first offense. Just like sentencing guidelines in court. There are a range of penalties a judge can pick from, depending on the individual circumstances of the case.
If you feel your Silence or Suspension was in error, you can appeal. They don’t let you argue your side, but you can get another person to review the game logs/chat logs.
