Creating a test user in facebook, I attempted to enter 1900 as birth year (which is mandatory), and was greeted with a red banner reading “Please enter your real birthday”.
Considering that the birth year is a combobox and its minimum value is 1900, why having an invalid option in the range of options to choose? Isn’t it wiser to just remove 1900 from the dates, and saving some validation-time to the user?
And what if I am 108 years old and want to use Facebook??
UPDATES: Entering a single name isn’t allowed, and some surnames (such as “Application”) are disallowed as well. And being born in 1901 remains unacceptable.
