Those are almost great points, but not really though.

1) Did you even try to give us a chance? If you'd go to our official explorer you can easily find the rich list. I'm even happy to give it to you. Here
2) You'd just have to take us for our word. But there are many people who where here from day one that could tell you that they also mined a ton.
3) How would we prove that we didn't mine. There is no proving negatives, I hope you understand this.

Hope this helped. I'd also like to point out that your 2nd and 3rd point are basically the same point.
