I have encountered several batches for review that are marked unreadable , but when I tried to check it , all are readable. I hope indexers will be responsible enough not to mark the batches unreadable . Those are persons not just names .
Thank goodness we have reviewers who can either enter the correct data or return the batch for reindexing which i am sure you did! Sometimes new indexers might find a record challenging, so we are there to back them up and make those corrections. When we make a significant amount of corrections, the batch is sent on for another reviewer to insure that there are no typos or missed data.
For those who don't know about the work that goes into reviewing and correcting indexing errors, I have attached a link to a knowledge article:
