Learned today, pay attention to the wise words on the forum! I tried about 10 Classify This "is this a webpage" hits, and got 2 rejections (although I am sure I was correct) so that's my one experiment with majority rules hits. At least only 2 were rejected. I wonder why they set up majority rules hits anyway, they won't always be accurate.
I'd still be going these if I could. I used to make $10-15 a day off of them. For some reason no matter how many times update java, it isn't good enough for these hits. You just have to be willing to toss anything questionable out. Assume that the other turkers are illiterate and have no idea what 404 means.
