That seems like a request from a data subject. I was responding to a comment that said you will only be sued by a regulator if you ignored them. There are multiple blog posts and articles that regulators have posted about what they will and wont do that is not codified.

thats not it. From my understanding people say that because that is how the UK regulator has dealt with cases in the past. But there is a different regulator in every EU country

"The controller shall provide information on action taken on a request under Articles 15 to 22 to the data subject without undue delay and in any event within one month of receipt of the request. That period may be extended by two further months where necessary, taking into account the complexity and number of the requests."
