I am getting emails, from people I know, one in America, one here in Britain. Some have attachments and are full of stuff I know full well those two people would never indulge in.
I delete them on arrival, never take the trouble to read them save from the opening lines....phutt! Gone.
Another scam for persistent mailers is to ask you to confirm you do not wish to receive further contact from them....answer those and they know you are at home.....I delete those unanswered too.
Most info on people has been offered, by themselves!.... Play dumb....use the delete facility.
