Admins, consider deleting all the accounts that haven't been used for the last 6 months or more with Brand New, Newbie (with 10 or less posts/activity) and banned and abandoned accounts so that a lot of usernames will be available and also it will free up some space (I don't know where).. 
.... 
.... It is not like we are having any performance issues now with "too many accounts".
So, are there any real benefits for such account pruning?
