Definitely not early days, but when i was a kid (early 2000's) the Internet was wildly different. I remember watching all of Lost on ABC's website for free. It had an ad at the beginning. That was it. Nobody self censored, and the Internet was widely considered a place only for adults, so most sites didn't even censor. Hell, i remember there was a subreddit of people having sex with corpses. There was definitely a lack of censorship.
There was almost like the wild west in the 2000s. There were rules, and established sites, but if you wandered long enough you would find a small site that just didnt fucking care at all.
Also everything ran on flash and that shit crashed all the time.
Yeah, enjoying made in abyss is similar to appreciating hitlers artwork.
If you didnt know, the creator is unapologetically a pedophile, and certain scenes are about as close to pedophile torture porn you can get and still be able to broadcast it.
Still a good show, but very difficult to justify that.
