For those who wish to delete their Humble Bundle accounts in light of the recent slopification, I can confirm the "Delete via Webpage" instructions here work:
https://www.justdeleteaccount.com/view/humble-bundle
You fill out the DSAR form, wait for an email from Ziff Davis. They reply via a stupid "Privacy Portal". (But I guess you only need to view the reply if your deletion _didn't_ work.)
And yes, this worked even outside of a country covered by the GDPR.
EDIT: Oops, fixed screenshot size.
