I filed a GDPR deletion request with Twitter a couple of weeks ago. It was quite a challenge to find a way to contact Twitter (for anyone who wants to you can do so via: https://secure.ethicspoint.com/domain/en/default_reporter.asp) - but I finally succeded. I did not simply wanted to deactivate my account I want all of my data to be deleted as is my right through the GDPR.
A couple of weeks later I received message saying that my account had been deactivated and that I should not log in as this my halt the deletion. Today (one and half months later) I tried logging into Twitter and found out that my login email is still registered).
I filed a new complained but wanted to know if anybody here has had their data successfully deleted? Twitter makes it deliberately hard to do so and this might be a violation of the GDPR.
Or you could just let it sit there, set it to private, maybe unfollow everyone, then access it once a month just to keep it live, and be an inactive lurker. He hates those.
