If there's an issue you can make your own community with blackjack, and hookers.
But at the same time these communities never seem to get super big (minus a few) and if you're subscribed to both there's not a good way to deduplicate the posts. So 5 communities post the same thing (or one person posts them in 5) sometimes you see all 5 side by side.
MBin reportedly combines them. Seeing as how the content is identical, Lemmy could too if someone would code it up to make it happen. (Though Rust is a difficult language, unlike Python.)
