I dislike receiving comments on minor typos on long pages. I've gotten a comment on a page that I was otherwise very happy with about a single period missing from one of the sentences. That was the comment, nothing else about the page, just about a minor punctuation error. 
On a different site I made a joke that a character can fire a bow with one hand while running away, which is obviously not possible in any realistic circumstance. This one-off joke became the source of constant nagging comments telling me to change it or remove it because of how unrealistic it is, for months. Instead I doubled down and had him do it several more times throughout the story >
Years ago, 2 decades perhaps, there was a girl who drew great anime art. This was at a time before social media and communities gathered in forums (just like this one) more often. This was a small niche community for game making software and to see really good anime art style was so rare in this community that it stood out. But of course, you had that one person asking for some cartoon porn. I still shake my head about that to this day.
The more things change, the more they stay the same.
Any variation of when are the humans coming. Including when will the humans be build by the robots.
Some of PTS from humans.
Most can't exist if humans are around because they are considered dangerous.
There are no secret humans of cloning labs
Humans be GONE.
I don’t get a lot of comments however, which makes some people think they are clever for posting “First”, which I usually just delete.
I have got some misgendering of characters.
Not quite verbatim but "This would be so good if it was a hetero relationship like God intended it to be." (Actually, is this still minor? 
)
I get those a lot of the time and I've taken to actually answer them with either congratulations or anything witty I can come up with. Sometimes, I've managed to get a conversation out of that 
Fan theories can be wild.......XD.
Some people may have wrong theories, but is still fun to see how they reached those conclusions.
My main character is nonbinary and uses they/them pronouns. A few readers (mostly not from tapas) have felt the need to comment on how awkward they find this. 
I’m Filipino and English is my 3rd language. I know the meaning of “his” and “her” but I usually make a mistake with my characters pronouns when I write and thankfully my readers are very understanding when I make these mistakes. I’m very blessed. I hope your readers can try and understand your characters. Mine is clearly my mistake but yours is just created like that and readers are pointing out how they feel uncomfortable about it 🥲🥲
Yeah, and it could totally be that the people in question don't live somewhere where this is a common thing. I'm just not someone who would leave negative feedback if a critique wasn't specifically requested, so I find it a bit irking.
Complaining about the pronouns is really too much. They are not forced to read if they don't like the characters...
I have a related, but different problem. I am NB but at this point in my story, all the charcters already presented are cis. But (I suppose?) because of my identity, several people are confused about the gender of several of my characters, especially my main one (my profile pic on the forum). He is a he, but gets a lot of she and a few them.
I don't mind, and I know I don't draw very gendered. But it's peculiar. Sometimes it makes me feel that I'm unable to write binary characters 
. But no hard feelings.
If your series has anything remotely similar to a popular anime series, people will jump on you like you're the first person to draw inspiration from something else. This persists even if the similarities are minor and it's only for a short portion of the entire series.
It is unrelated to my current comic, but the most annoying comment I got happened at an anime convention when I was selling hair clips that I had made.
The clips in question: Angel wing hairclips (Gaia Online...that is how long ago this was). I carefully sculpted them to clearly be a matching pair that would sit on each side of the head. The pieces that went up for sale were resin-cast replicas because they were lightweight and durable.
A young woman walked up and scrutinized my clips. She took one of my business cards and I thanked her for stopping by. She gives me a look and says, "I can make these myself." I wished her luck in doing it.
A week later, I get an email from her. She wants to know how I made a mirror copy of the hairclip because she could not sculpt a matching pair, so I must have a special technique. I tell her that there is no such technique that I am aware of, and she will simply have to work to make both sides match. She got mad at me for hiding an easy technique, and told me that I was full of crap.
It is such a silly situation for such a trivial thing, but I still wonder if she ever figured figured out how to get her mirror copy without sculpting it...and I am still a bit miffed over it.
