This question is not a well formed question. It's about net locations, IP and MAC addresses, logins and emails. You can't force someone to use their name. If such a standard was imposed, people would merely make up fake names. Better to just let them have the random anonymized handles they prefer. Do you know how risky it is to post online with your real identity? There is no limit to data retention with many of these companies online. As the major data brokers continue to consolidate and violate privacy with indefinite data retention, you'll see everything you've ever done online, one day in a central repository of data. In the US we're seeing a beta test roll out of something similar to the chinese people rating programs, taxing dissidents, denying participations of citizens if they don't agree with government, etc. The better question is why can't we be completely anonymous, and why does Disqus need to track and record our IP addresses?
