Love your comment on YS/Cint. I agree with you, they totally suck.
Qmee is notorious for late declines. Every time I get one, I email their support to complain. Pretty much all the survey sites do this. Forthright and their partner surveys are awful. I sent them four emails in the space of one day because of this. They give the same sorry excuse. We are not their customers in the end, just the poor slobs that get repeatedly screwed. Their actual customers are multi-million and billion dollar conglomerates who pay them handsomely. It will always be this way.
