How long does an area have to be flooded for before it's considered a body of water?

I can't read a news article anymore without thinking of how many upvotes I'd get if I posted it to Lemmy. People are fucking dying. I suppose the scoring mechanism is a way to distinguish higher-quality posts from lower-quality ones, but I also wonder whether "humane" social media like Lemmy blindly adopts techniques from mainstream social media that serves to increase engagement and profit. I wonder what a radical anticapitalist rethinking of social media would look like.
