bad characterization of character with no redeeming qualities yet still ends up happy without consequences of their actions, bad love triangles, tsunderes, cliches storylines, cheap plot where its just sex and no story, where one of them cheats and its apparently okay,where uke is weak and frail asf, and harem, where everyone attacks uke for a piece of his ass or where everyone is attracted to him.

Killing stalking is yaoi? why? ╮( ̄▽ ̄)╭
Pedophilia, shotacon, rape/abuse to love, misoginya, machism, biphobia, stupid/unnecessary missanderstandings, too much fluids during sex (yk?), uke/seme trope like almost every BL, lazy narrative, misconception of BDSM, glorification of toxic relationships without a second lecture....

Omegaverse and bad or incredibly old art.
It's very odd, I don't like omegaverses because most of the time, it portrays rape in a deserved or controversial light. It conflicts with my morality although I know it's fiction. I'm actually fine with reading actually terrible rape because we all know and it's implied that it's immoral. Funny enough, rapey semes from normal yaoi manga only sometimes put me off because I think the uke can sometimes techincally get out of those situations. I think what sets me off is the fact that omegas can be knotted to basically their rapists and/or rape is dismissed in that universe because it is hard for alphas to control themselves.
I'm just very picky with art nowadays and I can't really do much about it. It kind of sucks because I might be missing out on a good story because I'm solely judging it on the art. For example, I used to love Sekaiichi Hatsukoi but now I can't even read the manga anymore because the art (and the stories now I guess) kill me a little.
These are just my preferences. You are free to like what you like and I'm not going to bash you for it.

Sekaiichii hatsukoi has an horrible art. It distress my eyes and the story is based in the most stupid misunderstanding I have ever read in a story and from that circles of the same situations.
Old style art used to mean bad and cliche/boring stories so I associated it and cant handle them either with exceptions.
Omegaverse is like a lobotomy in manga form. Fate and free rape to make lazy yaoi mangakas to thnk even less about their stories.

I really wonder how you find yaoi manga to read ( ._.)
I swear that 98% of yaoi manga have at least one thing you dislike.
I wouldn't be able to read much yaoi manga if I had your preferences and I'm already nitpicky enough that I've run out of new yaoi manga to read :/
(I'm not bashing your preferences, I'm just genuinely curious as to how you find yaoi manga that you're fine with.)

i agree. i do like the concept of omegaverse because i used to read it in fanfics and whatever, but ever since it came to the manga world, it been a shit show. its all rape and its a hierarchy. it seems that people only like the story because the omegavese label is slapped onto it, even though the story is like any other typical non omegavese story. and i cant believe some morons on here actually want to live in an omegaverse world. and yeah, sekkaiichi and junjou is just getting old and boring. its like any other story, except the others are condensed into one volume while sekkkai and junjou are long and dragged out.

hold my apple juice i have a list
- age gaps
- illogical rape (uke falls in love and forgets about the fact he was abducted, abused then raped)
- body design makes no sense
- children are included
- the dudes look like women
- it's a fanfiction or dj
- incest
- bad story line
- the characters are stupid
- the story is overdramatic
- the story has 0 logic
- the characters are just dull
- it's just fucking and then they're lovers (I want some development)
- Really bad art (eyes are oversized, faces look weird, no body proportions)
- dude has a harem
- tsundere ukes
- one of them never stops the other dude or even attempts to
etc.

Hold my green tea
most of my favorites are shounen-ai, but here are my yaoi favorites lmao. they might break some rules but i let it pass just cause it was super funny or super cute.

dunno if y'all will like those, but these are my preferences.
What are things that make you instantly put down a yaoi? For me it's incest (even not blood related) large age gaps and rape/abuse...im curious what it is for fellow fujoshis
