For instance, user252244 has asked twelve questions in the three days they have been a member and ten of them have been closed. That's an 83% close rate. These generic "userXXXXX" accounts seem mostly inactive but when they are active they seem to ask a lot of poor questions.
These account names also indicate a minimum of investment in becoming a productive member of our communities (that they didn't take the time to choose a unique, meaningful or memorable username might imply that they won't take the time to formulate useful questions).
Need anything be done about these accounts in general or do we continue to handle them on a case-by-case basis? Can anything be done that is more useful than a "please choose a meaningful/memorable username" suggestion and a reiteration to read the FAQ before asking questions?
