Google Plus Custom URL Selection - Could Google have made it any more painful?

Google Plus is "Allowing" me to select a custom URL, but it feels that any name I suggest including weird ones like Badrinathafwez are a very common name (apparently too many people have it).

 I wonder how they came up with the stupid algorithm/logic that determined that random weird names like Badrinathafwez are common.

Btw Google Search for that name returns the result "No results found for badrinathafwez".

Unfortunate that Google Plus team hasn't done a good job at using Google Search skills to determine if the name is common or not. Anyways after trying 20+ meaningful and weird combinations , I give up , I don't want a custom URL on Google+.
