I started mturk 3 days ago. Have done 166 HITs already, and for whatever reason, I already have a rejected HIT, which is from a title called market research survey. It dropped me to 97%. I don't know why it was rejected, but I messaged the requester, with no response. Will that rejection stay permanently on the account or will it eventually go away?
It will stay forever unless it is removed by the requester (or in very rare circumstances, by Amazon).
