Why do people still have doubts about Vgchartz' accuracy?

[Neos]

Ok so i regularly watch the nintendo forum and they often post vgchartz' numbers, so i think cool, publicity and such. But the strange thing is, a lot of people still see vgchartz as some site that pulls random numbers out of nowhere. Below here you can see 2 random examples of it. So my question is, how can we as a community give Vgchartz a better name on the internet?
