It can be banned for sending unsolicited messages.
Permanent ban is a most possible consequence for that newbie account.
How is it unsolicited?
Account sales are allowed but it is discouraged and of which it should be discouraged. So what
doesdid the newbie
diddo wrong that his account should be banned?
I do not think the account will be banned. But what that is important is the red feedback that he has received. That is enough.
The red feedback will discourage others from doing the same with a reputed account.
