the method is very simple, join some traffic exchange sites and surf to earn credits.
Join some PTP sites and promote your PTP link in the traffic exchange sites.
search cheap VPS providers, so that you can use them to surf 24 hours a day.

In that way you will earn a few dollars, with not much work.

If you want earn some more, you can use a bot with SSH socks proxy support.
I have such a bot for ebesucher.
I modified the bot, so that it works with other traffic exchange sites.

But I don't want to post it here in public.

I only want to give you some ideas how to earn money.

If you have any questions, you can PM me.

btw. if you are not registered in any good TE and PTP sites, I could give you some sites.
