You can follow Lemmy communities from Mastadon but not the other way around. And it doesn’t work well anyway.

You can use Kbin for both Lemmy and Mastadon.

But Mastadon content is not very Lemmy-like so if all you want is the BBC toots, but not a Mastadon account, you might as well bookmark bbc.social and scroll it occasionally.
