Scraped data of 2.6M Duolingo users released on hacking forum

Just got a notification from 'haveibeenpwned':

Breach: Duolingo

Date of breach: 24 Jan 2023

Number of accounts: 2,676,696

Compromised data:

Email addresses, Names, Spoken languages, Usernames Description: In August 2023, 2.6M records of data scraped from Duolingo were broadly distributed on a popular hacking forum. Obtained by enumerating a vulnerable API, the data had earlier appeared for sale in January 2023 and contained email addresses, names, the languages being learned, XP (experience points), and other data related to learning progress on Duolingo. Whilst some of the data attributes are intentionally public, the ability to map private email addresses to them presents an ongoing risk to user privacy.

Which site have they released it on? Couldn't find it on the few I know.
