That’s the same portal that they expected us to use to report what a shit show GDPR enforcement has been the past 4 years. The irony was the site demanded more information than necessary – thus the site asking how is the GDPR going was itself infringing on data minimisation. It’s fussy about who hosts the email address they force you to disclose. I eventually got an account after revealing more than I wanted to and then the JavaScript doc submission app gave vague errors anyway and could not be used. It also forces periodic password changes which seems a bit over the top for this sort of mission.

tl;dr: not everyone can have their say. Only some people.
