I am a member of a couple survey panels. I find that most don't pan out or are total scams. I found this website today: Survey Police. They have people rate the many, many survey sites out there. I looked at the two I use. The one I like the best got 40% overall rating (not so good). And the other one I use got over 80%, which has yet to pay anything (but I like the surveys they send so I still do them).
I think the survey companies may have people write that they are good even if they aren't. I saw one post say that the company asked them to make a post on this survey police site. So, it's up to you to decide. I didn't find anything useful, but I might browse again ever now and then. I don't think I would use it to try a new survey site, based on the ratings my websites got, but I think it would be a good place to see if a survey website is a complete scam.
Do you do surveys online and do they payout?
