I never ever saw a 1500cr survey in 3 years of doing them. I am lucky enough to get 126cr surveys. Lately I cannot access them at all, cant get past the Agree to Access button at the bottom of the page.
I sent a message with screen shot to both Peanut Labs and WGT but heard nothing. Dont expect to hear from them either.
My very uneducated guess is that these surveys are going the way of the dinosaur....extinct.
