Unique accounts should be required. But not "real names". The problem is that many HR departments (I know of at least one that does not admit to doing it but I know for a fact does) will as part of their research/vetting of a potential employee actually check for the name/email/phonenumber on resume on MANY online sources (myspace, facebook, google, and USENET) at the very least.
The problem is that once the information is out there, there is no way to control what it is used for. Many poeple that were active on usenet in the 90s would never have thought that their posts would last longer than the longest USENET retention period of the time. Google ended up purchasing dejanews and all their backup spools (http://googlepress.blogspot.com/2001/02/google-acquires-usenet-discussion.html) to be included in googles archives. [BTW; Google also aquired MANY other backups of USENET spools from other sources as well to round out gaps in their archives]
- An innocent comment about "Apple" now for example may cost someone their job in 3-5 years when Apple buys out the company that they work for which is currently competition...
Another problem that I have with Real Name requirement is that it would make it extremely easy for the crooks to impersonate someone and commit identity theft.....
