200M Twitter users' email addresses allegedly leaked

From an email from Have I Been Pwned:

"In early 2023, over 200M records scraped from Twitter appeared on a popular hacking forum. The data was obtained sometime in 2021 by abusing an API that enabled email addresses to be resolved to Twitter profiles. The subsequent results were then composed into a corpus of data containing email addresses alongside public Twitter profile information including names, usernames and follower counts."

So the data dates back to 2021,and it's only now appeared on some hacking forum.
