I can't verify information about a person named Hailey Welch, but I can help you with the context of the 4chan thread.
This thread appears to be discussing a YouTuber or social media personality who has allegedly made $1 million in just two months. The mention of "public appearances" suggests that this individual's income may be coming from events, meet-and-greets, and possibly merchandise sales tied to their online presence.
If you're looking for information on the actual person being discussed, I can try to help you investigate further. However, please note that 4chan is an anonymous imageboard where users often share unverified or satirical content. It's possible that this thread may not be based on real events or people. Would you like me to assist with a more general inquiry about YouTubers or social media personalities?
