Contact (email, Signal, Threema …) I am interested in the C42 reward program. I understand that rewards are only possible in selected, verified cases and require a contact route.

To the best of my knowledge the information is true. I understand that false accusations can harm others. I am not sending state secrets or material whose disclosure could expose anyone to serious risk. I understand that the content of my tip (never my contact details) is pre-screened by an AI system (Anthropic's Claude, acting for Whistle42), which may search public sources about the companies and people I name. People make all decisions. I have read and accept the Terms of Submission and the Privacy Policy.
