Currently less than 1/4 of the votes on this post (the post itself) are from users subscribed to this community. Hexbear users far outnumber us, it's not even remotely close. With 5 out of the 8 instances with over 1000 monthly active users having defederated them, we are showing up much higher in their All feed. Lemmy.world defederated them, and they have more users than all the other 7/8 put together. Over 2/3rds of lemmy content is no longer available to them, so they see our posts about random NZ stuff, and decide to comment on them. Because there are so many of them, it floods the posts.
Basically, it takes us from being a community of NZ and NZ-adjacent people, to being a community of international hexbear users talking about NZ. It completely changes the tone of the instance.
It's not something they have done (other than whatever made the others want to defederate), but the point of the fediverse is to curate who you federate with in order to build the community you want, then people join the instances that curate the way they want. I'm not so keen on a community of hexbear users talking about NZ. The occasional one was fine, but to have our threads swamped is just not what I'm here for.
Also, hexbear users are filling all the posts from different instances trying to decide if people want to defederate or not. It's bad taste.
I try not to be a "my way or the highway" kind of guy, but I haven't yet seen a good counter-argument to my other post.
