There being none of my favourite work available, I checked out this CrowdFlower HIT: https://www.mturk.com/mturk/preview?groupId=2PBKA0RYNJ92VBPPRZ2MNTUP40838I Verify if the social networking site listed is officially connected to the business details given. After 2 HITs I've been kicked off the job for lack of accuracy. The two questions I got "wrong" according to them, I should have selected Yes and I chose No. I chose No, in both cases, because the link did not take me to any social networking site, both were Page Not Exist in Facebook. The instructions clearly said to choose "no" in this case. Honestly, don't know why I even bothered.
Look at the bright side - you will get paid despite the "wrong" answer and it was just a matter of time before getting caught like you describe.
To be honest, I keep running into issues with CF hits, unfortunaly their name is relatively close to CrowdSource and I love their hits!
