It is support -- kiwifarms isn't a free-for-all, they have their list of "lolcows" (people who have a thread dedicated to them), and only moderators can add new threads.
So only moderators can add new threads, and I assume users can post in threads, and I assume the users are the ones posting that the people should kill themselves. So how does this translate into the moderators or site operators/owners endorsing the content of user posts?
Edit: to be clear, "allowing content" does not entail "endorsing content" per my original reply.
