not homestuck but i've found a lot of luck in wcarpg, which is a warrior cats roleplay forum with fantasy aspects :) rp spaces definitely still exist, it just takes a while to come across the right ones esp depending on what exactly youre looking for!

i do think a rp forum would be good, most rp spaces have chilled out a lot and i havent seen a lot of weirdos in roleplay spaces for a while in my experience. this site's community in general seems to OVERALL have its shit together from what ive seen
