Do proxys earn cash?

[Super]

Are proxys a legitimate way of earning cash?

I have seen many people earning through adsense on their proxy sites.

After reading a lots about proxies, I decided to give it a try.
Just created my first proxy site. A good hosting its hard to find if you want something cheap, just like warez hostings.
I promoted a bit and made a few dollars, so I think with the right promotion you can make some nice money out of it. Its much easier then other businesses I had done.

How can you find out if the major filters blocked your proxy?
