Firstly, it does not appear that there is a meta or community community for the instance, so this looked to be the best place to post this.

It appears that only the admins from the instance are federating outwardly to other instances.

I was browsing some of the communities here with my main lemmy account and started to notice that none of the posts were actually from mtgzone members. I did see posts from Mike and Andrew (I forget the format to tag), but everything else visible was posts from users from other instances. I checked to see if it was just that instance, and tried one of my underused accounts from a larger instance and still nothing.
