Haven't done any survey since the 12th, tried to do some today (forgot weekends should be avoided).
Picked the surveys from the account screen because the invitation emails stopped coming since we had a long international trip back in Oct thru Dec, hence could not take survey from the invite. Then it stopped when we were about 2/3 in the journey and never resumes.
Anyway, today I got 4x 0.20 survey then a $5 survey that miraculously went all the way to finish. After that I got 3 unqualified survey with 0 payment. To their "credit", they did say that on the front page, and the disqualification went rather speedy. Though I am not sure next time when I see the 0 payment I would even bother to go thru it, based on last time when I was disqualified as "enough participants" when the survey was 87% completed... Though upon complaint, a rep did credit my account despite she claimed that I was indeed not qualified (but the reason on the screen was "enough participants").
I just hope certain hotel and airline programs would become participants so I can use this as the activity generator to keep accounts alive - that is my main purpose of doing this.
