Ran into another problem with a task. This time it's a 15 point offer for searching some casino on Google. The task asked if I found it on the first 5 result pages, which I did not. So I selected no and hit submit, but the task insisted I have to provide their phone number and visit the page. So I googled more to find the casino (tigercasino) and visited it. After adding their phone number the task still complains. I even went so far as to install their casino software in a virtual machine; still the task won't accept my submission.

To me it seems as if the higher paying tasks try their best to get a job done without paying for it simply by complaining about non-existent problems. I guess the task provider simply hopes that users won't go into a lengthy email discussion just to get a few cents, especially when the user has to deliver proof of his work.

If more such questionable tasks appear, users will quit working because of such hassles with the task provider.

Btw, is the "Contributor Id" listed in the help menu unique to a worker? So in case crowdflower acknowledges a complain and pays points to this id, will I receive the bitcoins for it?
