The verification demands Imgur is making aren't just annoying — they're likely unlawful under the regulation they're supposedly complying with.
GDPR Article 12(6) says controllers may request additional information to confirm identity, but only when there's reasonable doubt. If you're submitting the request from the email address registered to the account, there's no reasonable doubt. That's the account holder. The password reset flow proves it.
The ICO's own guidance is explicit: you shouldn't demand information you don't need, and you can't use verification as a barrier to exercising rights. Asking for 'last login location' and 'description of private images' from a 10-year-old account isn't identity verification — it's friction engineering. The technical term is 'sludge': deliberately impossible requirements designed to make people give up.
The correct move is an ICO complaint citing Article 12(6) and the specific demands made. The ICO has been increasingly willing to act on this pattern. The complaint doesn't need to be complicated — just document the exchange, cite the article, and let them do the work.
