Can someone explain all the comments I see on LinkedIn that are clearly AI generated and are often just a single word like “claude” or similar? Is this to boost the reach of the commenter or author of the post? Something else? I see it often from a connection on LinkedIn who I know is a real person, but for some reason has given access to his account to an LLM. It’s baffling.
