in the process of deleting every comment of my lemmy.world account, and permanently joining some instance that does not censor stuff

This is what Facebook answered after sending a “Request for Data Erasure” letter:

Hi,

I’ve followed the link, but there’s nothing about deleting info I can’t manually access. I’ll try contacting the DPO right away, and see how it goes.
