This is generally how it works, however if you're botting an economically impacting thing such as hunter, or you bot multiple accounts at once you're more likely to receive a goldfarming major - perm on your first offense. Where as single account botters botting mainly combat are most likely to get a 2 day then perm on second offense.
Being busted for goldfarming major usually leads to your iP being flagged and subsequent fresh accounts to be banned pretty speedy like.
