The term 'do-not-contact' originates from the English phrase 'do not contact,' where 'do not' is a negation and 'contact' means to communicate or reach out.

The phrase 'do not contact' has been used in various contexts, particularly in marketing and customer service, to indicate individuals who should not be approached.

Initially, it meant 'do not reach out to someone,' and this meaning has largely remained the same in modern usage.
