I have filed a GDPR complaint about Facebook with my local data authority, because Facebook deleted my account, but still send me newsletters suggesting people to follow. I filed it January 2024 and only after 10 months did the complain get forwarded to Ireland who, because of some new rule, now has to handle the complaint. It will take for ever, but i don’t really care
The EU have made laws regarding the right to be forgotten. If the companies breach this, they face huge fines, as a percentage of their overall earnings. That said, I am loosing faith in how often they get enforced and how easily you can complain to the authorities about it.
Also, i am in doubt of how much data they can actually maintain, while anonymizing it. So they may keep your data, but remove any personal link to you as a person.
