Week long study- you complete a survey at the end of each day for a week. Pays $10! Cassie Mogilner is the Requester and the title is Week Long Study. Not sure how many HITS she had posted! You do have to give them your email but i've done that for surveys like this before with no problems.
Yeah i'm not sure when they went up. I logged on this afternoon and there it was, snagged it quick and then posted on here.
That happened to me the other day. I accepted an $8 survey HIT, and by the time I logged in here, it was already gone.
I'm constantly refreshing when I'm searching HITS cause I always start with most reward first- and the non-scam bigger amounts go fast unless it's insanely difficult. I've lucked out a couple times but most of the time I accept the HIT and it tells me no more available...luck of the draw I guess.
