Also, stay away from Univox and Tap Research surveys.
Normally, if you get past the initial pick survey screen, if you screen out, you get 5 credits for your time. Not with these two! They keep sending you to other surveys, getting bits of info for free, and you NEVER even get one 5 credit award, although they have tested you for half a dozen surveys.
Plus, recently, Peanut Lab surveys ask for your full name and address. WTF? Surveys are supposed to be anonymous. Like I really want these people sending me junk mail or looking up my phone number so I can get endless trash phone calls from India and Pakistan.
WTG should NEVER allow ANY survey that asks for name, address or e-mail info.
