You're gonna have to point to part of the regulation where thats not allowed. there is a mechanism for deletion. so long as its done within 30 days its still within spec
The overall point being that if you want to use a product/service, you'll look past minor violations of local regulations on account deletion or charger bundling.
GDPR has nothing to do with friction I beleve.
Our lawyer told me that GDPR also applies to paper records, so there is some real-world friction right there.
The important part that there is a right - in whatever good/broken process it is enveloped is irrelevant.
Moreover does HN host PII data? Not if you don't give it to them.
But deletion requests are not so strong: if you make people really jump through hoops then you might get in some trouble, but the expencted standard is basically at 'sending an email and getting a result within 30 days'.
So additional validation would surely be subject to friction.
