This is of course a horrible thing to happen, but.....
the reality of our modern lives is we do sort of 'sign up' to mail shots, spam, etc etc every time we give a company our details. These companies, with an eye to the bottom line, outsource the mail-shot/spam to the cheapest supplier. Would we really want our ELC toys to cost 25p per item more just to ensure that someone, somewhere, is personally checking each spam email/mail shot for this sort of occurrence?
If it were US who'd lost a child, maybe. If it was everyone else, we might say 'Um, no'.
My dad was still receiving circulars, spam email, mail shots and yes, demands to speak to him personally 3 years after he died! We just shrugged our shoulders, in the end. We recognised none of it was personal or malicious, it's just the way these things are.
Finally, I am a HCP and I am often a little surprised at the enraged phone calls we get from (often) widows, decrying our insensitivity, as they receive letters telling their recently deceased DHs to attend for tests, sometimes arriving only 48 hours after the patient has died.....
