I deserved some rejections for not reading the places I’d subbed. But I learned fast that I was being obnoxious. Recently I rejected a submission because it was very similar to a story I had published a couple of weeks prior. He responded:

Ya, I’m not really someone who reads nanoism regularly. How far should I look through your archive before submitting instead of wasting our time again?

Thanks for your honesty, man. You just did. I hope your new to this game.
