I often give fake info as an extra measure of data protection. If I don’t need the data controller to have my date of birth, I give a fake one.

Well this just screwed me because I made an access request and the data controller said: to verify your identity, tell us your date of birth. Fuck me. I didn’t keep track of which fake date I gave them. I didn’t even keep track of whether I gave fake info. So they could treat my otherwise legit request as a breach attempt.

I should have kept track of the birth date I supplied. I will; from now on.
