I don't think it's OpenClaw or OpenAI/Anthropic/etc's fault here, it's the human user who kicked it off and hasn't been monitoring it and/or hiding behind it.
For all we know a human told his OpenClaw instance "Write up a blog post about your rejection" and then later told it "Apologize for your behavior". There is absolutely nothing to suggest that the LLM did this all unprompted. Is it possible? Yes, like MoltBook, it's possible. But, like MoltBook, I wouldn't be surprised if this is another instance of a lot of people LARPing behind an LLM.
