Beware of this one: Take a survey on clothing for different situations by Fracti !!!! I've done a few hits for this requester with no problem, however I did this survey on clothing. It was about 7 pages of bubble questions. I got the code and went back and it had expired!! FOUR minutes for 7 pages of questions!!!! I wrote them. And also I forgot to do my trick of starting the survey and only accepting the hit when everything looked good/almost done. Since I finished it enough to acquire a code they should have to pay.
I did the same one and had the same problem and I let the requester know it. The only problem is that I didn't get a code.
