I've seen that kinda crap all the time, but WOW, that's a new low.
And I'm not even exaggerating. It really got to me at the time. I caught myself wondering if my story was any good - or if my readers were just ignoring pages without any hint of "ship sailing". But yeah struggles of having "fujoshis" reading your content.
I haven't received any hate comments (YET), but I have received some annoyingly cringey comments. Some people get too excited when I introduce a new character, and assume they're a love interest to someone. Even though, I thought I was being pretty clear as to who the main focuses were?
So far there hasn't been any bullying of my characters, or any BAD comments persay, but it's annoying nonetheless. I'm just waiting for the hate to eventually flow in. (As they do on any comic, but a lot so on ANY form of BL, I've noticed.)
God those kinds of people annoy me to no end, I'm not even an author, but I'm sick of seeing tripe like that. Especially when it's on a scene or situation where it shouldn't even apply or factor in. Like you know, when the scene involves conversations between two people about past SUICIDE ATTEMPTS! I really do hope whoever posted that was downvoted heavily, and that sentiment was not shared by a good deal of people. Ughh...
I had a scene were a character killed someone, and realized that it was someone that he not only knew but was very close to.
Character was distressed and horrified.
Had a reader in the comments hypothesizing the next page(s) were/should be 'the character fapping'
Because that's what I want to do after potentially killing the most important person in the world to me. Just whip it out and start pounding it.
Edit: There was also another time, where two characters were going to have sex but stopped because of -character development and emotional plot- With someone in the comments complaining, saying things like stop talking and demanding to 'go back to sex' on several of the pages. (heck even if they did 'go back to sex' it would be implied and then faded out to another scene, because I don't draw sex scenes)
Readers asking you to tell them the resolution to a main conflict in the comic... Like sure, let me just spoil this event for you that's been built up for four chapters...
For me, it's usually the one-word comment. I figure, if you're gonna bother to comment, at least give me something worthwhile to respond to.
There's also those who just want you to draw the worst things ever that are their fetishes >3>' I put "accepting requests" on DA, but as soon as I did I got a bunch of over-the-top fetish stuff requested.
There are some real horror stories on here. I haven't gotten any bad comments on my work yet but I find myself periodically coming back to scan this thread, just to steel myself for if and when the day comes 
I will say that the comments of people complaining about having to pay for premium comics REALLY rub me the wrong way - though not as much as comments that direct other users to read licensed premium comics on illegal aggregate sites. A whole site full to the brim with free content and people still feel the need to act like that? Jeez...
They've been spoiled by all the seemingly-free content that's available online. Now they think that the stuff just materializes in people's servers.
"Are you high?"
No, I just have imagination. Sometimes I draw "trippy" stuff, because I like weird things.
I've been really lucky with the comments I've gotten so far, especially here in Tapastic. Mostly people are incredibly nice and polite!
However the one thing that I've run into several times is people telling my comic reminds them of Firefly. Like I get there are similarities but honestly, I'm not even that familiar with the show. I wouldn't be so bothered if people told me my comic reminded them of something I have actually drawn inspiration from, like Cowboy Bebop. But being told my comic is similar to a show I don't even know that well makes me feel kinda awful because the similarities are not intentional.
Don't feel bad. We've reached a critical mass when it comes to pop culture and everybody can't help but riff on everybody else. Firefly was a good show, so it's a positive comparison.
Thanks for the encouragement! I know we've reached the point in pop culture where everything is similar to something and I don't think readers really mean it in a bad way when they compare things. Still, I really would rather be compared to the sci-fi stories that did inspire me because then at least it would feel like it was intentional rather than accidental.
I suppose the hipster solution would be to search for the really obscure source material.
"I only take inspiration from medieval Welsh literature. It's pretty academic, you've probably never heard of it."
comments/reviews that are literally nothing but a single emoji or like "update more" like what the fuck am i supposed to say to that???? like give me something i can reply to so i don't feel like a jerk for not replying

"When the next page?"
"You're so awesome!!! Unlike me, my work fucking sucks!!!!"
I hate both of these comments. One is someone who is too impatient to wait and thinks they're entitled to demanding things from me when they're not paying for anything. The other is someone who gives me the impression they're fishing for a reassurance (whether that's true or not, that's how I see it).
If I ever got a message like the first one, I will be super petty. I will make a journal about these every comments and link them to that journal. Every time someone asks me that, they get a link to the journal. If you're not paying me for my time and effort, you don't have a right to ask me to "hurry up"
The second one, I'd probably be more softer with. I won't lie, as a kid, I used to do the same thing. However, I didn't know at the time how upsetting this can be to an artist and I grew out of it. No one wants people to feel bad about their level of art skills, and that's what an artist gets when they see these comments. These are not compliments to me --if I have to reassure you because you're insecure about yourself and to not make myself seem like a bad person, it's not a compliment. I'd probably give some advice, but I'd also tell them flat out "this isn't a compliment and here's why".
