Like all companies there are editors who are very picky and others that are not. I do shops for a different msc ..about 20-25 per mont. In over two years I have never gotten anything but a 10. Then last month the editor asked me to put in a ton of info that did not seem required or never had been before. This was over three or four requests that kept escalating the "required" answers. I fixed them all but it took a long time and got an 8 on every shop. That was I hope the first and last time that I will deal with that editor. This month I am back to 10 on all my reports again.
Like the shopper who said a company should not be judged based on what one employee did that was bad, this is true of editors as well. We all have schedulers and editors we would like to avoid as some of them are harsher on their shoppers than others. Bottom line it would not hurt to call and ask if you can be reinstated. This may have happened thru an automatic algorithm but it may have been a real person making the decision to drop you and if someone else looks it over they may reconsider.
