Legal loopholes hamper fight against spam

Li Shuang often ignores messages sent to his cellphone.

"I get at least 10 spam messages every day. Some have investment advice or inform me that I have won a big prize. Some even suggest prostitutes are available. All are annoying," said the 25-year-old, who works in a Beijing finance company.

But legal loopholes are hampering efforts to tackle the scourge, and legislation must be enacted to close it, experts said.
