As mentioned throughout this topic, you wont make an income from these sites unless you can advance program yourself which I will mention in a bit. Why?
Because, lets say you read an email and earn $0.02 per time (this is also a very generous amount). You dont need to actually read that email. Just click into it, and then click the link in the page to activate the $0.02.
Now, each email you receive would take about 30 seconds to complete, including the clicking the email, scrolling down and clicking activation link, waiting on the window to open, closing it and deleting that email). Infact, 30 seconds is doing it in good time too.
Great, but...
That would give you time to complete 120 emails in an hour, which would generate you $2.40 per hour. Just a tad lower then the minimum hour rate I'd say. To top that off, you would be lucky to receive 5 to 10 of these a day, and I stress the lucky part...
In relation to the survays, they act much thee same. "Complete this survey for $0.50". As above, it could take you up to 20mins to complete one of these survey. Earning you a cool $1.50 an hour!!!
I believe you would be better off filling out a survey to the local college science department. They might give you a fair doller for use of your body???
Anyhow, as I was saying above. You might make $50 a week, at most, by completing these money making schemes. But thats when you sign up to over 50 different sites. So thats about $1 per site which I believe is average.
I remember setting up an account with one of these scams a number of years ago. I believe I got my balance upto about $6 or $7 over a number of weeks. Then, as these sites do, it closed down because it ran out of advertisers. The minimum withdrawl was $25. And I was a long way off this mark.
I rest my case...
