This was just discussed in the EdenTasks thread
and, while I won't reiterate everything said there, it does take a lot of time to edit a poorly written review. Some reviews come in so riddled with typos, poor grammar or spelling, or sentences that just DON'T make sense that I know
sometimes I've spent more time on that review than its originating writer.
We have the incentive of the free toy to write our monthly review, but editors have no other incentive but points to edit reviews. And, honestly? If I was getting a hundred points to edit some of the reviews we get, I'd decline to participate in the program because it truly DOES take time. For every review that we glance through, to which we make one change (or, God forbid NO changes...) there are three others that take a minimum of ten minutes.
As to reviews coming back riddled with errors, you have several options there. First, you can rate the editing job as being done poorly, and then you can contact EF staff and point out that such-and-such is consistently editing reviews poorly. I do, however, really want to stress that some reviews come in REALLY badly written, and that sometimes we DO miss things because we've corrected "it's" to "its" about fifteen times, and removed excess commas, and added in periods and missing words to a single section.
