I know Lemmy is about to take off because the porn is quickly moving from drawn henti and furry images to gonewild onlyfan contributors. I call it the QOTP Index (Quality Of The Porn). Reddit is done.
It's pretty easy. Just don't go to lemmynsfw.com. hopefully, we'll get a way to subscribe to block all communities on another instance with a single click at some point to make this easier.
NSFW communities don't show up by default. You can create an account on that instance to view all of them, or visit https://lemmyverse.net/communities to search for your specific interests.
I was told I could create an account anywhere on the fediverse and it wouldn't matter, I'd see everything. If I need to create an account every time I want to see some booba, that's not very seamless. Can I not just subscribe and see it on this lemmy.world account?
This is all very confusing coming from the one-account-one-site "everything just works" of reddit.
You don't necessarily need an account on lemmynsfw.com - you would just need an account to browse NSFW on their homepage. But you can see and interact with all their communities from your current instance.
