Startrek.website was never primarily local traffic. It used to be mostly lemmy.world users posting Star Trek content to the Star Trek communities, a lot like dullsters.net, but less extreme.
The off-instance users mostly stopped posting there and moved to Ten Forward, because of that clique’s post.








Yes, I agree that most users were unaware, but most users also follow the leader-y types who have the strong opinions. Those three repost farmers worked together to move all the content over, and anyone who investigated was given the post with the transphobia claim as a reason. This locked in the network effect that made most people move over to Ten Forward, with little outcry.
ST.W did have legitimate moderation problems, but the problems with the Ten Forward clique are much worse.
