In the last days I spent a disproportionate amount deleting old accounts I found in my password manager, and mostly because so many companies - despite the GDPR - have rudimentary, manually when not completely nonexistent processes to delete your data.
In this post I describe my process going through about 100 old accounts and trying to delete them all, including a top 10 for the weirdest, funniest or most interesting cases I encountered while doing so.
Thanks. Absolutely my experience too. The ones where you can’t edit the email I noticed often used the email as username, and probably god knows how bad is the code on the backend.
