Around the time Google was celebrating its first decade, European lawmakers often focused on the premise that someone could ask for information to be deleted, and this was known as the right to be forgotten.
In my experience, most developers didn't believe it was plausible to implement anything like this. And, most legal scholar-minded people didn't feel that it was a sensible prerogative. After all, if Milo Yiannopoulos could simply instruct Twitter to delete their records of his suspension, he could go back to the platform.
However, in the ensuing decade we've gotten better at technology and administration. We now find it more feasible to delete people in a more complete sense, and the GDPR has forced us to consider it, at least somewhat seriously. Yet, in many ways it is just as, if not more, preposterous than ever.
