This may be an unpopular option since I've already seen it across lemmy, but the ____porn communities. I'd like to browse pictures of nice landscapes or exotic cars without worry about someone around me noticing "PORN" on my screen.
At this point it seems very old internet, something that made sense when those communities were established, but now is unnecessary gratuitous and not socially acceptable.
What from reddit do you hope to never see on lemmy?
i can't stand megathreads -- no one reads these! no one wants their posts banished there!
