Big mistake on the Internet World Stats is an International website

I so surprised when I access internetworldstats.com. On the "Top 20 countries with the highest number of users" table, Vietnam became Vietnem. It's a serious mistake. I don't know why?

We know that, Internet World Stats is an International website is very useful where we can find a lot of information such as Internet Usage, Population Statistics and Internet Market Research Data, for over 233 individual countries and world regions.

Now, we can believe  Internet World Stats is an International website anymore?
