Thanks. I think that is the same form I used the first time and basically the same as the link I gave.
It is clear that they are trying hard to make it complicated - that’s why I would urge anyone who wants their data deleted to try to contact them, to complain and complain again. In the end paying their support personnel will cost these companies enough money that they might consider a different practice. (As long as it is not simply a bot answering your requests - looking at you, “Bob” from Facebook support.)
If Twitter won’t comply in the next 30 days I will contact my national authority.
Does anybody also know whom to contact on an EU level?
PS: what’s GPA?
And that, kids, is what we call a perfectionist.
