There are many spammy survey sites out there but Pinecone is not one of them. The only way you can sign up is if you find a banner so many people are on the prowl to find a banner and guess what I have a banner here!
I did their surveys a few years back and they are easy to understand surveys. I would receive a check in the mail shortly after completing the survey. The process may have changed a little since but this is a quality, legitimate survey site. Easy way to make a little extra money sitting in your living room.
