So there's this guy who made a tool where someone punches in their bluesky or mastodon credentials to his website, and it auto-crawls their feeds and produces an LLM summary of everyone it finds posting there. He was asked what people should do if we don't want to be mulched as content for his summary feeds. He said we should block him. I replied, I can do that, but that only stops *you* from running the tool on me, how do I prevent *your other users* from running your tool on me? He blocked me.
