How do I contact the admin(s) of an instance?

I believe one or more moderators of an instance are acting in bad faith. As I understand it, Lemmy does not have a modmail function to address the issue with the team, so I need to seek out the instance admin?

How do I:

1. Find out who that is

2. Contact them

I see no indication towards either on the community's side bar and I don't think there's a support@[instance] community.
