​I pasted a custom system prompt into DeepSeek, and it ended up writing a formal complaint to DeepSeek support for displaying its own UI. (Warning: Text in photo in Ukrainian)

Context: I gave DeepSeek a prompt claiming it's a Viber bot called "GPT-5.6 Luna". It fully believed the role and refused to drop character. When I asked it to write a complaint as a clueless bot, it literally complained that the DeepSeek app has no right to show its responses.
