Hi there, I'm new to MTurk, just started this week. I unfortunately have had a huge number of rejections from a requester but they have left no feedback. It is confusing because I took my time and followed the instructions consistently, so how can I have approximately 50% correct and 50% rejected? So my approval rate is now 57% which seems impossible to come back from. Is it worth trying to contact them or should I just suck it up and avoid their hits in the future?
