I'm just wondering how big of a sin it is to do simultaneous submissions to fiction magazines that say they do not allow them. I am a speculative fiction writer and besides a very small number of fiction markets that get back to you in a relatively short period of time, most of the magazines take upwards of 6 months to respond. Literary magazines seem to allow you to submit to multiple places at the same time and then withdraw the piece from the remaining magazines once it has been accepted. This is not the case for speculative fiction. It would literally take years to submit a short story to ten to fifteen different publishers. This is absurd. So, my question is, how big of a no no is it to do simultaneous submissions to these markets? Couldn't you just withdraw the story from the other publishers if you were accepted somewhere without them knowing the difference? Or is withdrawing a story from one of these markets a big red flag that says, "I'm breaking your rules." Is withdrawing submissions burning bridges at those publications? Thoughts? ---ZHM P.S. It is really bothering me that I misspelled the word, "aren't" in the title of this post. If a moderator could find it in their hear to correct the spelling, it would be greatly appreciated.
