Last night I did ten hits for Sangwook lee - one hit was rejected, one hit was approved, eight hits are still in pending. (the hit that was rejected said I missed a paying attention question). Anyway this morning I received an email from Amazon that says: We regret to inform you that you were blocked from working on HITs by the following requester(s): Sangwook lee Requesters typically block Workers who submit poor quality work. Requesters rely on Mechanical Turk for high quality work results. In order to maintain quality, we continuously monitor service activity. Should additional Requesters block you in the future, we may suspend your account. Please ensure your work quality is at a high standard. We encourage you to read the HIT instructions and follow them carefully. We realize that this block may be a onetime occurrence for you. Should you maintain high work quality with no further complaints for the next few months we will dismiss this event. ---------- So is this a hard block? Did anyone else have this issue with this requester? The TO's looked good otherwise I wouldn't have touched it. I did add my experience to the TO as well btw.
