Considering server costs are maybe $50, doubtful they colocate, with 1m visitors a month, if not more now (ioi made a post about the increase in activity and it's exponential rates), I know from using adsense the average CTR is 2-3%. That's 20K-30K clicks a month. Average click is 5-20cents, you're looking at easily a grand if not 5 or 6.
It may not be any of my business, but you shouldn't expect things for free if you've got something with some serious potential, and vgcharts has some INSANELY HIGH potential.
