Not talking about a hacker. I am stating that the described hash dance offers no exclusion from GDPR as saying "we promise we won't look" would do.
My point about brute forcing being useless, is that you hold all the information needed to re-create the hash. All but one tiny piece that is the random number. so brute force is a very effective O(<tiny piece size>). And since it is stored in your locally available data, there is no rate constraints.
