Back in the day, we had a few members here who could sniff out trouble-makers and track them literally to their desks where they thought they were hiding while being malignant.

I have a friend who has been receiving veiled threats via SMS. The sender seems to be hiding behind one of those virtual SIM cards used by bulk-SMS providers (the no has 15 digits).

Is there anyone on the forum who would be able to trace the origin? Even if we can just find which company's bulk SMSes are being used, it would help.
