It's an interesting topic but this post barely covers it. The Wikipedia article on illegal numbers is much more informative and interesting. https://en.wikipedia.org/wiki/Illegal_number

The way this is written makes me suspect that the post itself would hash to an illegal number, but I don't have the capacity to check it out.

None of the major cryptographic hashes (MD5, SHA-*) have practical preimage attacks. It means pulling off what the author suggests (having a document hash to an illegal number) is impossible in practice, at least for now.

It could be possible using a non-cryptographic hash (murmurhash, CRC,...).
