This would be quite ridiculous if it was reality. One rejected piece shouldn’t disqualify a writer from submitting to the same publication or editor. I know I certainly wouldn’t bar a writer from submitting to my publication if this happened. People make mistakes, that’s a part of life. What gets to me is when writers are surprised by editors who are ‘nice’ and give feedback on a rejected piece. That is part of an editors job. Some don’t bother to respond at all, that’s what I find unacceptable.
