I'd be interested both 'does it use' and 'did it use cloudflare' (in the affected period).
"Live" is somewhat misleading here: the leaks are out there, in crawler caches. Do you consider such source "live", even though it is no longer leaking data?
I think that's exactly what the commenter was getting at. "Live" data would be deficient in this instance, historical data would be better.
