Who sent the short message "How many people can benefit from forwarding this message" and what is its purpose?

It was originally caused by the "M Plan" launched by Guangdong Mobile. The content is probably. Send a message D to 02758 to get a "seed message" and forward it to your friend, and your friend will forward it to others. Forward it to 20 people, and you can get the phone bill for 2 yuan. Do you know who sent this message first? But the activity is over. But there are still some sequelae of forwarding.
