work at home ads...is it for real?

i believe they are scams as i cannot even make 10 dollars on the internet. I mean - think about it - in real life - you can get paid at least $15 for doing a written survey for a company - as i have done. On the internet - i can't even make $5 in a month doing surveys. trust me friend, a lot of people will post discussions claiming that a site really works with an exclaimation mark at the end of it. These people are only attempting to promote their reference link.
