Pyoro, a prominent Nintendo leaker, locked their social media account after revealing that their source of information was an employee of Nintendo in Japan5. This revelation came after a report on popular leakers by Bloomberg, which noted Pyoro's unusual silence ahead of a Nintendo Direct event and their incorrect prediction of no big announcements. Further investigation by users on the Resetera forum led to the conclusion that Pyoro likely had access to Nintendo's web backend.
Forum members deduced Pyoro's source of information by noticing that, unlike previous Nintendo Directs, this week's announcements didn't have pre-seeded webpages on Nintendo's store. They realized that Pyoro's previous leaks had all involved games that were set to go live on Nintendo's website immediately after the live streams. This led them to conclude that Pyoro had access to Nintendo's web backend.
Pyoro was uncharacteristically quiet ahead of this week's Nintendo Direct and stated that they didn't expect many big announcements. This was unusual because their accurate leaks in the past had earned them a large following, and they were typically more active before such events.
