A few years ago I was unable to register a new Australian company via the automated systems because one of our directors has a hyphenated middle name and the various agencies concerned normalised this in differing ways, leading to rejection at a validation step. Resolving this turned a process of a few minutes into a multi-week telephonic saga.
I subsequently learned that many folks faced with the same problem simply didn’t bother and instead left intentionally erroneous/incomplete (but consistent, and thereby validating) data in the registers.
