. . . you're telling a bot to stop linking something. It automatically pulls top posts from Hackernews and rebroadcasts them here.
I get it that many Lemmy users came across during the blackout of reddit (myself included), but prefering Lemmy doesn't change the fact a lot of good discourse still happens on reddit. Not linking reddit self posts at this point would exclude a fair bit of content trending in the background on Hackernews, Linkedin, or any of the other large social platforms wihch all cross-post.
