omg great question!!! theres a couple things that i literally never read regardless of fandom because i have no interest in them like x reader, chatfics, extremely long fantasy fics, that type of stuff. i usually look for complete works, when im looking for quality i look for long (10k+) oneshots in particular, smut, and just specific pairings. i feel like i am actually okay reading everything if the ship or premise appeals me but i guess there are two i can think of right now that i tend to skip over in kpop rpf: either eggpreg or boypussy/vaginal sex. i am not judging people liking/writing these things, obviously I've done similar or worse myself but i personally just pass over them! otherwise i read everything, like dubcon, angst, mcd, omegaverse, college au, toxic dynamics, age gap, etc are all okay with me if the premise/ship is appealing enough
