Should not accept names that only contain numbers

[bryanhce]

The app should have shown a warning or an error when a name that contains only numbers like "123" is entered as this is not a real name.

Team's Response

There are many names today that contains numbers, for example Jennifer 8. Lee

We also know what Elon decided to name his son. In all, we believe that if we were to restrict these names, it will be Overzealous input validation because who knows what someone is going to name their child next

Adding a specific method to check SPECIFICALLY whether a name contains only numerals is therefore unnecessary and not meaningful

• [x] I disagree

Reason for disagreement: I agree that names do contain numbers but that is not a the point of the bug that I am reporting. This is also not overzealous input validation as names should not purely be numbers. Such names are simply not valid. Your email checking criteria is not considered overzealous, as seen in the chunk of text below, so how can you call having 1 more valid additional check on names being purely numbers, overzealous?

Fun info: Elon's son, X Æ A-Xii, cannot be added into your app because of the special character! There is also no numbers in his name.
