Hi there. Thanks for pointing that out. My blog is usually read only by a bunch of nerds and when I put the first cookie banner, GDPR was not even a thing. I've added one that is compliant with the spec. Hope it's fine.
There are still 4 cookies set, including "euconsent" (set to some weird value), and "__cfduid" which I assume is some kind of unique identifier.
I don't know if you're serious about implementing GDPR compliance, but this isn't.
