Yeah they target work phones because people have to answer more frequently. A message or call that is sent to a work phone that goes opened/unanswered then it looks like someone is slacking.

Most personal phones people just let go to message or just delete (without opening to evade image based tracking) unknown numbers, with business or work most numbers are new or unknown.

Sucks how they target them. Any phone number or text recipient they send to that answers/views will get more and more and more spam.
