I also occasionally have fun injections in my online profiles, and at some point of time it even worked. For example, more than 1 year ago there were few "Show HN" entries for "Analyze any HN profile" and "Analyze any Github profile" (using AI), and silly injections worked. Modern LLMs are a bit smarter than that, but who knows, maybe we'll see some novell small language models that are still prone to these injections.
