I feel that it takes FOREVER to make any money on InboxDollars. If you work really hard you can get some money. I found that survey websites are mainly gunning for your personal information. There are some cash rewards sites that do have a legit system but I could only find cash crate:

This website has the survey option, but it also has other ways to getting paid without giving too much personal information. I usually reach payout 4 out of 5 times just for 5-10 minutes a day.
