Clickbait article misattributes this to Taylor herself, when in reality this was caught by her father, a financial advisor of 30 years at Merrill Lynch.
Additionally, do you have a source for the claim that her father was the actual person that "caught" this? I did a small search and did not find. If it is just a presumption based on his career, a more charitable take along these lines might be that she could have learned about securities from her dad sometime over those 30 years and thus could have not needed to consult him to know the question to ask.
It's not some obscure detail, it's one of the key risks of being involved in a new crypto offering as an investor, and I think most people posting here have read years of HN discussions about the relevant SEC positions. Ultra high net worth individuals - especially ones that have launched multiple business lines - are fairly likely to have heard about it. At least enough to play word association and ask someone to look into it for them.
