There are two types of ignoring that's been very common with the american and swedish companies I've battled with.

1. Protection against law suits. We reserve the right to not delete any information you have, since if there's a law suit we would need that as proof.

2. Freedom of speech. We are a publisher, so by removing your personal information, our right to free speech is threatened and since this is a foundational legal principle, it overrides any GDPR laws.

Adding to this, I tried to do the same thing and after providing uuid2 they said "we don't know where it is, but if it exists we will delete it" or something like that, which of course is ridiculous because you can f-ing access the database and access the unique identifier. I'm gonna do it again in some time and try to file another gdpr complaint as soon as they tell "me nooo we can't do that silly ahah"

Until some DB leak happens.
