This reminds me of the often used internet debating technique of attacking people according to their "name". How many times have you seen people on UNSENET, Slashdot, various web forums, LiveJournal, and other places, get angry because somebody posts a comment under the name "Anonymous"? The attack basically goes in a few ways such as "Stop being an Anonymous Coward", "Use your Real Name and own your comments", "Stop hiding behind a false name"', and so on.
The problem with these attacks is that on the internet, basically everybody is anonymous unless they specifically try to announce to people who they really are. Who really knows who you are on the internet? I'd say that your ISP knows, because presumably you pay them for internet access, so they've got your credit card number and name. Even in that case, there is no proof that the person putting a message on the internet is the person paying for the internet access. It could be somebody who lives in the same house, or a visitor, or even a burglar.
Internet access is also available from internet cafes, public libraries, educational institutions, or being close enough to an unencrypted wireless access point. What it comes down to is that if somebody chooses an internet nickname like "Purple Bunny", "Sparky The Wizard", or "Myxomatosis", you know that's not their real name. But what if somebody chooses a name such as "Bob Clintock", "Frida Johansson", or "Moira McLean"? Those might or might not be their real names. People can choose any string of characters they like to use as a nickname on the internet.
Therefore, it is rather pointless to demand that people on the internet refrain from posting anonymous messages. Everybody is anonymous by default. Even when a person uses a name that appears to be a real name, such as Fabio Heinz for example, it could still be a made up name. If somebody posts an anonymous message you don't like, you can either ignore it (which is often the best choice), or else debate the contents of the message on its merits, ignoring that the author chooses not to attach a string such as "Snail Guts" or "Belinda Roberts" to the top.
On the internet, there is no requirement to use your real name in many situations. You're probably better off not using your real name and details of your life if you wish to avoid problems such as stalking and identity theft.
