An anonymous reader writes "Having entered my personal details (full real name, home address) to websites with an 'https://' prefix in order to purchase goods, I am still being sent emails from companies (or their agents) which include, in plain text, those same details I have entered over a secure connection. These are often companies which are very keen to tell you how much they value your privacy and how they will not pass your details on to third parties. What recourse does one have to tell them to desist from such behaviour whilst still doing business with them if their products are otherwise desirable? I email the relevant IT team as a matter of course to tell them it's not appropriate (mostly to no avail), but is there any legislation — in any territory — which addresses this?"
