Hello everyone - and thanks for your questions. I've taken some time this week to go through everything on this thread and dig into all the nooks and crannies - so apologies for the delayed response.
Back in April, I explained on this thread that while we’ve certainly had our fair share of security incidents, the suggestion that we’re cavalier with users’ data is, I believe, untrue and unfair - we’ve always been transparent and upfront about any data breaches, however small and inconsequential (unlike many orgs who routinely swept things under the carpet). Please take a look at my post on that thread as I hope it will provide some reassurance.
However, it’s also fair to say that we have not been following what we understand to be best practise wrt to the removal of old email addresses from our email system when users change (as oppose to delete) their email - we should have been removing the old emails from our mailing list, not just changing them on our site database and that indeed was an oversight on our part. We have now fixed this and I apologise for any concern caused.
It remains the case that we are always more than happy to manually remove any email from our list, so please do contact us if you have any concerns at all. And please be assured that de-registration is and has been working as it should - if you deregister your account it removes all details you provided at registration, including your email address, from our data-base and all our mailing lists.
Thanks again for raising this - it is always helpful and we're always happy to answer questions about how and why we store your data.
