This are straight "Nigerian" scams that are sent by email as well as text.  They are now targeting Avon and Mary Kay reps, as well as photographers.    They don't know you personally per se, and send a mass email or text to hundreds of reps.  They play a numbers game just trying to hook one or two targets.

The way to respond is to simply ignore them and spread the word to fellow reps raising awareness of this scam
