I moved my account to Ireland (in a somewhat improperly researched attempt to force them to delete my data due to Ireland’s data retention laws), waited a month or so then scripted deletion of all the images and posts on the account, changed all details and disconnected it from everyone and everything, then waited a week or so ‘deleted’ the account.
That was about 5 years ago (and it was a great life decision IMO) but - people say they still see me popping up on their feeds with my (fake) birthdate, memories (which I was untagged or had privacy settings disallowing me to be tagged in) and other weird things.
I’ve been careful not to mistakenly log in once which I fear my bring the account back from the dead and I’ve also kept an eye to make sure there’s no identity theft / fake account going on.
I don’t trust that company one bit, I’m glad I left but I don’t for one second believe my data’s actually been deleted.
While I truly hope something open source and decentralised gets momentum, I still truly love twitter - I get a lot out of it and I’ve met and networked with a lot of great people through Twitter.
