I received the text message offering part time job with monthly salary of 5,000 to 30,000 from 0432 975 525 (also reported) on Monday 20 Sept with email address a713701 @ xiaosizhu.com.
On Tuesday same text message but number now 0432 991 657 and email address 15567 @ xiaosizhu.com.
Google search for xiaosizhu.com only returned several people with that name, no company.
