That is not innapropriate...

I am asking if it falls under "inappropriate usernames" section or not.

It does not

But is the username example above be considered spammy?

Sure, but usernames don't fall under any kind of spam rule.

Does the username having only one alphabet as mentioned the same above falls under spam and inappropriate usernames?

As I said before, it does not.
