I see a lot of suggestions

of ptc sites, and chat sites etc. But how long would you really have to spend online to make a living at it. What about those which actually want you to buy something in order to start earning. isnt this a way of cheatng ? When I worked in the office, other than the clothes I wore, and the fuel to get there, I didnt have to buy anything to earn my paycheque. Is there any genuine paid to chat sites, or online earning sites where you could get a weekly or by weekly cheque?
