There are legit sites and fakes, I did find a legit one, but it took a fortnight to earn £5 and then another fortnight for them to get it to my pay pal so I felt a bit cheated. If you are going to use one, don't give them any information except a paypal email, they can't do anything with that other than send you payments. Don't give them bank information, and use a seperate email address than the one you normally use, and add it to your paypal as you don't want your real account spammed. The answer is you can make a bit of money, but not much.
I saw one...they paid you 17 cents per response, you had to get a minimum of 1000 responses.
sure, if you consider "making money" as 5-25 cents per survey completed
Yes of course they are some opportunities that come on line and if u do them u can be paid or get gifts and many things.
no, not anything to speak of. pennies an hour maybe if you're lucky
