In those days, being feminist meant being "sex positive" and lots of amateurs did porn just to show how liberated and empowered they were, especially in college.
This was before Kardashians, trans obsessions, and body positivity, so no glorification of fatties or weirdly disproportionate tits/asses. No trannies shitting up hetero threads out of jealousy of hot real girls. Just girls like you might see on campus or at a concert. Before disfiguring body mods and tats were mainstream.
Also 4chan had more tolerance for mainstream beauty standards. Like there were milf threads back then, but guys into 30-40 year olds didn't shit up 20 something threads just to destroy anything that wasn't their thing. Lots of lesbian threads, without shitting up from "they're not real lesbians" or "if you like lesbians you're gay" or shit like you get now. These days it's more about shitting up threads for stuff you don't like rather than posting stuff you do like.
It's all extreme. Fattie threads, skelly threads, but few threads with just slender, healthy, conventionally hot girls.
tl;Dr: in the 90s and 00s, porn chicks tried hard to look normal. In the 10s and 20s, normal chicks try to look like 3rd world streetwalkers.
