I'm confused too. Without context, it looks like an excellent piece of advice, and a publisher cannot do much about the fact a work (even a good one) does not fit the type of work they publish.
Unless, of course, it does fit what they publish but they used that easy way to reject.. Don't know, don't know context.
I got this comment on the very last episode of the previous Web-Comic I wrote. (I am providing a print screen of the comment below.)
I was in a bit of a shock when I first read it, but thankfully it was the only one among many positive comments so I quickly got over it and moved on. This comment made me understand the saying, you can't please everyone, so just write for yourself. Make sure that if at least one person likes your story, that person is you.
The hurtful comment said:
Beyond this one comment, I have received many other comments from people (but usually in private) telling me what they didn't like or what they believed didn't work in my stories. I always see such feedback as opportunities to get better and none of them has actually ever hurt me yet.
I have also been lucky I guess, so far, to hear from people that were professional in their approach and they either didn't want to hurt me or were kind enough to take the time to offer constructive criticism that helped me understand their P.O.V and helped me become a better writer (or I hope so anyway 
).
As for rejections, that others have mentioned, yeah I received plenty of those as well, and even though they can sting, they are unavoidable and anyone who is serious about being a writer (of any kind) will have to learn to deal with them I think. The worst I ever got from being rejected was a temporary lack of motivation before I got back to writing again.
That comment made me think of the old ladies at church who would let their toddler read the book of revelations in the bible whilst simulatiously claim tom and Jerry is too violet for their 13 year old and get it banned.
Dunno seems just a random nutter, who no one should take seriously.
"better let the murder go free...."
Yeah the would definatitly stopped Hilter, lynches of innocents and the toy box killer. 100% 
Some people need to go outside and look and the less fortunate from time to time... gives one some perspective
That random image is a sample of a rejection letter.
To aspire to be a professional writer rejection is part of the profession and each time it is a hit on morale after having put in the effort. to submit a piece.
thegrinder.diabolicalplots.com is one of the many sites that writers find publications to submit their writings to, if you wish to experience what is being refereed to,
Well....rejection can hurt, but gotta say the rejection of the example above was done in a tactful way.
I don't know in what field you work, but in science, getting your work rejected is like... the standard xD You can even find the rate of acceptance of journals online, and for the majority, it's very low. It's nothing personal against you or the people you write for. Also, if impact factor is important in your area are you're new to it, you may wanna start by reading the journal's scope and some of their papers to get a better idea, then do a list with the journals you'd like to publish, start with the one that has the highest IF, and go down from there once you get rejected. Just a small suggestion, there are websites with more comprehensive advice. If you know all that then please disregard my message ^^
Also:
May I ask what scientific journal pays for their papers? It's the other way around haha
damn, I'm sorry you had to go through that
Not to get too personal my story's similar in that way, where its kind of a therapy
and I've heard so many people tell stories similar to yours that at this point I'm just kind of expecting someone to tell me I deserve to get assaulted for having my characters go through that or that their experiences are unrealistic when they're based off mine.
like Idk how someone can say that and still consider themselves a good person.
I think the most hurtful feedback ive ever gotten was simply "this is shit why do you bother" nothing else no criticism or anything. Made me stop writing for a while though.
Can't say, Never wrote for any.
Best way to go about it.
A spoof sample found on google, though similar in nature to.
I don’t feel pain, only disappointed….
That being said would anyone like to be my first hate comment?
As a comic writer it was something like "I am getting bored with this, do something interesting" - all while the character just got out of torture by hunger and self-torture by exercise to stab the torturer and be stabbed back with more dire consequences. All because they wanted the torturer and the tortured to...make out. (which didn't happen)
It felt mostly hurtful because it felt like they are flexing power over my creative intent, and I am obligated to comply, but because I don't, they return again and again to "help me" by reminding they want this and everything else - even character's literal suffering is not important and boring.
As just a writer it was not the feedback but lack thereof. X) Idk maybe during the time in my country it was okay to not even send back a rejection letter even if writer spends money for it. However, they always could blame postal service.
I got a couple of these bad boys from one commentator:
Along with a couple other comments that are more nitpicks so I won't show them here. Kinda weird cus as you got further into the pages, his comments turned from stuff like that to more questions that suggested that he actually got invested in the story.
May I add he actually subscribed to my series after all these comments, and he's still subbed today.
You didn't really leave any actual critique, but okay.
Not writing but once a guy told me to off myself for covering Madonna's "Ray of Light". I like to tell that story because it was so shocking. Turns out his whole soundcloud was dedicated him trolling everyone who covered Madonna. (Granted, the cover was done years ago so it genuinely wasn't too hot but still. Yeesh.)
Also, once a guy slammed into a post I made on Reddit, simply leaving "this is dumb" and vanished. Somehow that spooked me even more than if it had been actual critique. Why was it dumb!? Tell me!! (Honestly though, I'm always all for real critique. It has made me a better creator!)
Would have been great if I really did receive feedback, but it’s something too expensive to ask for nowadays.
An old thread of mine about Webtoon ratings thread recently got necro'd, and reminded me of one.
Being told my comic deserved 5 out of 10 stars on Webtoon. That really stung... I knew what the person meant by the comment, and I'm certainly not pretending that my comic was flawless - there's a lot in those early episodes I intend to change, once I have the time to re-work them. But anything under an 8-star rating on Webtoon is an anomaly, and unless the comic is new and small, and has been rating-bombed, it usually indicates there's something really weird about the story and/or art. When the 'standard' low-ish rating is 8 stars, 5 is catastrophic. (If the rating system weren't so warped, I'd have probably agreed it was fair.)
I think they thought I was just trying to get attention as well, whereas I simply wanted the rating to go back to something normal-looking, so new readers didn't see the rating and assume something terrible. I didn't expect the thread to blow up the way it did, and I was pretty new at the time... Nevertheless, I wasn't expecting the comment, and it really knocked me about. More than the rating bomb did, since I know that was just a random Reddit troll, and this was a fellow creator.
It's water under the bridge now, but yeah, that wasn't a fun day.
Nothing is pointless if we learn from our mistakes and grow better from them. Thank you for your kind words. Humanity is learning but at an excruciatingly slow rate.
Yes, her expectation pretty much told me what she was hoping to get from me. I do get descriptive enough that I mark chapters like that as "Mature Content." I even mark the paragraphs for the reader to skip them if they wish. Still, it's nothing graphic. I've seen worse in cheap romance novels in supermarkets. I'm not a prude. I have written erotica. I think, however, there is sometimes a call for it and there sometimes isn't. This book doesn't call for it, and I'm happy with it the way it is.
Thank you for the compliment!
