The platform I use to serve this blog, ghost, has introduced a new feature that cannot be deactivated: memberships.
Since I do not want to have any personal data about you, I have tried to remove all the references to signing-up so we can avoid a misunderstanding. In the case there are some left, please DO NOT REGISTER/SUBSCRIBE to this blog.
The best data protection practice is to not request nor store any unneeded data.
In any case, I would recommend to apply this practice in all your projects and live. Ironic coming from someone in the data and analytics field, right?
