My best was a $9 transcription hit. I don't remember anything being particularly troubling about it. Yesterday I saw a $10 transcription hit, I was going to do it but I just didn't feel like it once I started.
I saw a hit that paid 50$ to sign up for an adult website that required you to pay 28 $ for the website registration and after you should give the username and password.
I saw one a few days ago that paid 40$ to register on some site. But i dodnt have 95% approved HITS to accept it
I have seen a $90 or $99. There was one translation hit about 4 months back. Just recently there was one for $40, but you were required to pay $24 out of it to some site for completing the task.
The most I've seen has been like 10 bucks or so for a 500 words article. But the one I earned most from was a 4.56 HIT if I remember it well. It was for recording a short video. Easy money, babe!
The highest HIT I have seen is $10 that asked to write street reveiws. I have also seen similar HITs that pay $7.50. I haven't tried them because I thought it's too much work.
I saw a few hits for 40 dollars back in September when I first signed on. But you had to live in the Chicago area, visit a specific store, take pictures of the inside of the store and download them.
I have seen a hit that was for 50$.. it was a long time back about 3-4 months. At around the same time a class mate of mine accepted a 100$ hit and also got paid.
I recently complete a transcription of an interview that paid $25. Got paid a few days after completion. This is the most I have ever made on a HIT.
I completed one that was for $35, but I received a $115 bonus That's the most I've been paid on mturk. I worked my butt off for it though.
The highest I've been paid is 1.50. I have a pending one though for 2.50. I just did it, so it hasn't been approved yet.
