How do I take over an abandoned community?

There's a particular community that I'd like to take over, which has been inactive for over 2 years. One of the mods was last active two years ago, and the other never even made a single post. I've reached out to them to be added as a mod, but I haven't received any response.

Is there anything that the Lemmy admins can do about this? I'd hate for Lemmy to be in the same situation as Reddit, with bunch of abandoned subs with inactive mods and subs getting filled with spam.

Thanks!
