I'm a fairly new user to MTurk and new to this forum, so please forgive me if I am posting in the wrong place. I reviewed the rules and my question does not seem inappropriate for this forum. I have been seeing rejections in my dashboard that I cannot figure out and the Requester provides no feedback. I'm super careful about my HITs to make sure they are accurate, but periodically they are rejected anyway. I send messages to the Requesters to get feedback but I never hear back. It's disappointing because I know I do the work accurately, even at the expense of being slower and making less money. It feels like theft of my time, and I'm disappointed because it is damage to my reputation.. I know of a few HITs that in hindsight I may have done wrong, but I've done about 1,000 HITs so far and my rejection rate has been about 1.5%. My rejections all come from the same 3 Requesterst. I have sent Amazon feedback but of course I got no response from them either. I am no longer working on HITs from those Requesters. Has anyone experienced problems with bad Requesters like this? Is there maybe a list of bad Requesters that I can review so I can avoid bad ones that will arbitrarily damage my reputation?
