I've been using peanut labs for 6 years now. I have seen them improve over time. In the beginning I had the same issues everyone here is describing but nowadays my experience is totally different. I rarely get disqualified now and if I do end up being sent to a bad survey I still get awarded compensation for it. Maybe it has to do with where im going from (Video game sites) perhaps its not peanut labs at all and is the surveys they link to? I don't know. All I do know is I've had a very good experience with them for many years and while the payment isn't high I don't think its peanutlabs that sets that. Its the survey sites offering it.
My one complaint about them however is that I have not gotten a response anytime I sent in for support for surveys I did complete but didn't get awarded for. Otherwise I would of given a 4 star.
