Don't know where to ask but what is our affiliated Mastodon instance?

I remember seeing someone mention there is a Mastodon instance for Hexbear, but I don't remember what it was called. I got kind of bothered by the one I was on (kolektiva.social has a lot of cool rad people but it also has too many unserious people with "tankies fuck off" in their bio), and someone I want to follow blocked the entire kolektiva instance because he was getting harassed by too many racists from there, so I'm looking to make a new account. Hexbear has proven to be the best part of the fediverse I've found so far and it'd be nice to make my new Mastodon account there too.
