Although the proposal still doesn't solve all edge cases. And the current edge cases have presumably found a solution, like my girlfriend that has 2 last names, and is from a 'western' country.
My parents address is stupidly long and doesn't fit in to most address boxes, so you also need to allow arbitrarily long addresses.
Oh, and your email validator is wrong too.
Now, I'll admit: it actually did thwart my attempt at not providing my actual email address, for a good several attempts. I had to increase my creativity to a level I truly didn't anticipate, before finding something it accepted. And I definitely had enough randomness that it wasn't just disguising an "already exists" error with an "invalid address" error for privacy purposes, I am certain.
What in the world kind of validation is this? Do people really end up resorting to entering their actual email address often enough to make this at all useful?
To understand this as an English speaker. Imagine people aren't called John Smith, but rather John the Smith and not Bill Boston but Bill of Boston. Now imagine that a large percentage of people had an infix in the name. It would be impractical to order stuff by last name and find a massive index on the letter "o" because all the last names starting with "of" or at "t" starting with "the". To balance this out, parts that would translate to words like "from", "the", "of", "to" or "on" would be considered an index. Part of the last name, but not considered part of the name index. John the Smith would be found at the letter "S" usually structured as "Smith, John the".
It's the iTunes "The ..." problem.
Thanks for clarifying.
