Why do some websites pay people to take online surveys? Is there a catch?

This is the best website for doing surveys I've ever used. It's simple to learn and easy to make lots of $$. http://www.treasuretrooper.com/358839

This site actually has a forums and testimonials of proof that they give you whatever you want from ebay and amazon with the exception of weapons and pornography http://www.rewards1.com/index.php?referrer_id=165904%09%09%09%09%09%09 This site is the same but does not offer forums but still has testimonials =] http://www.prizerebel.com/index.php?r=327424

ive done cashcrate before, i worked my tail off for like 5 nights straight and got like 10.70, at least it was real money, i cashed it, but too much work just for that, AND the thing with it was cashcrate had to wait until the survey company confirmed that i had completed it, so i ended up doing like twice the amount and half did not get confirmed, its better if you can convince more people to sign up for them under YOUR reference number that way every person they sign up you get like a dollar, basically a pyramid scheme pretty crappy, but at least i got paid for 5days work, not much though, oh and some places actually call you if you give them your real phone number

The catch with things like this is usually that they hardly pay you anything. You might end up making about $10 a month if you're really lucky. The benefit to them is that they get their surveys filled out practically for free. If there are special offers (such as a free magazine issue or things like that), they are hoping that you won't cancel them before they can charge you money or that you will like the product enough to pay to keep getting it.

so you want to make money online? survey's are mostly Scams,i wonder how you got a reasonable one... but the pay is never huge no matter the time you devote. try affiliate marketting...the place where the most internet cash resides.you pay nothing to join (talk of zero risk)and no further investments,you get paid for the referrals you bring in. just you making cash all day no website needed...how can it be any simpler? http://kacno.livejournal.com details of the most profitable markets available

u kno wat i dont kno

There are a couple of websites that I use, and just recently got a check for 41.90 and 48.00 I havent noticed any type of catch yet. They have all my real info and I dont get any calls no spam email (just ones offering the surveys). With this one, I only do the surveys that offer money https://www.surveyspot.com/join/Join.faces?VendorID=33&OptInSource=usgen&locale=en_US the one that I really like is https://www.opinionoutpost.com/index.php... you get paid for every survey you complete with them (if you qualify)
