In late April 2025, 4chan experienced a significant data breach nicknamed "Sharty" involving the leak of emails belonging to Hiroyuki Nishimura (moot), the site's founder, and other 4chan janitors (moderators). The leaked emails contained personal information, private discussions, and internal 4chan communications. While the exact extent and impact of the breach remained unclear, it fueled speculation and discussion within the 4chan community and beyond regarding the site's security practices and the privacy of its users. The hack also resulted in various memes and jokes related to the leaked content, particularly targeting moot and the janitors' perceived incompetence.
The author claims to have found a vulnerability in YouTube's systems that allows retrieval of the email address associated with any YouTube channel for a $10,000 bounty. They describe a process involving crafting specific playlist URLs and exploiting how YouTube handles playlist sharing and unlisted videos to ultimately reveal the target channel's email address within a Google Account picker. While they provided Google with a proof-of-concept, they did not fully disclose the details publicly for ethical and security reasons. They emphasize the seriousness of this vulnerability, given the potential for targeted harassment and phishing attacks against prominent YouTubers.
HN commenters largely discussed the plausibility and specifics of the vulnerability described in the article. Some doubted the $10,000 price tag, suggesting it was inflated. Others questioned whether the vulnerability stemmed from a single bug or multiple chained exploits. A few commenters analyzed the technical details, focusing on the potential involvement of improperly configured OAuth flows or mismanaged access tokens within YouTube's systems. There was also skepticism about the ethical implications of disclosing the vulnerability details before Google had a chance to patch it, with some arguing responsible disclosure practices weren't followed. Finally, several comments highlighted the broader security risks associated with OAuth and similar authorization mechanisms.

The overall consensus leans towards the story being a fabrication, possibly an elaborate troll or creative writing exercise.

The Hacker News post titled "4chan Sharty Hack And Janitor Email Leak" linking to the Know Your Meme article has generated several comments discussing the incident and its implications.
Several commenters express skepticism about the veracity of the leaked emails, pointing out the lack of concrete evidence and the potential for fabrication. One commenter questions the authenticity, stating it "sounds like a larp," using internet slang for a live-action role-playing game, implying it's a fictional narrative presented as reality. This sentiment is echoed by others who find the story unbelievable and too neatly packaged. The commenters highlight the absence of corroborating evidence from sources outside 4chan, further fueling their doubts.
The discussion also touches on the nature of 4chan and its culture. One commenter mentions the site's history of elaborate pranks and hoaxes, suggesting this incident could be another example. Another points to the inherent difficulty of verifying information originating from 4chan due to its anonymous nature and fast-paced, chaotic environment. They emphasize the importance of treating such information with caution, particularly given the lack of independent verification.
Some comments delve into the technical aspects of the alleged hack. One commenter questions the plausibility of accessing email archives through the described method, implying it seems technically improbable. Another speculates on potential vulnerabilities and methods the hackers might have exploited, but acknowledges the lack of technical details available to confirm the claims.
Furthermore, some users comment on the humor and absurdity of the situation. They find the narrative, regardless of its truthfulness, entertaining and fitting within the context of 4chan's often bizarre and outrageous culture. The term "sharty" itself is highlighted as amusing and contributing to the overall comedic value of the incident. Some users also note the irony of the alleged hackers' apparent motivation – exposing the perceived hypocrisy of 4chan's moderation policies – while simultaneously engaging in disruptive behavior.
Finally, a few comments express concern about the potential consequences for 4chan, including legal ramifications and damage to its reputation. However, these comments are generally overshadowed by the prevailing skepticism and amusement regarding the incident. The overall tone of the comments section is one of cautious disbelief mixed with a degree of amusement, reflecting the uncertainty surrounding the authenticity of the claims and the inherent strangeness of the situation.
