Good point.

I take back the request for you to name the sites, but my point stands.

There are exceptions, but making very substantial (which I define as over $10,000/month) income is quite difficult. And making thousands in a non-adult link farm is just incredibly difficult. Possible, of course. Sell Viagra ;)

And it is not normal for a new (less than 2 years old) non adult link farm site to make more than 1,000-2,000.

Would you mind naming the category, age and traffic level of the non-adult(s) that make more than $1,500/month? That'd be interesting.
