Basically what the title says. I absolutely detest Harems but I'll still keep Pseudo Harems here (MC isn't married to a lot of chicks but there's plenty who like and spend time around him anyway). I feel having Harems decreases the overall quality and its hard to talk about true love while the MCs banging 100+ women on the regular (which Chinese authors like to write about for some reason). I have no problem with Romance, although I do feel Webnovel authors aren't really cut out to write about it.

Some other things I'll exclude are ultra-nationalism (china numba 1!), Novels without Harems but the MC still plays around with/f*cks a lot of women

There's no real restrictions on whether it's serious or comedy, although comedy generally has more permavirg*n!MCs
