I used to use Swagbucks, but my knowledge is not up to date as I stopped nearly a year ago. They do not 1099 or anything, you are responsible for tracking your own earnings (or not, I'm sure most don't).
At my best, I was earning about 1 $25 gift card per month, however I was putting much more than 1hr a day into it. As a frugal person, I was almost always screened out of surveys, and many surveys screened out at the end instead of the beginning, so there's a lot of wasted time. Most of my earnings were from watching videos.
Whether it's worth it or not depends on what you value. I stopped because it was using a lot of our internet bandwidth, and taking a lot of my time. I find Prolific to have a better payout/time invested, so I use that instead now.
