you are directly accessing intentionally unpublished (internal) API with purpose of directly "reverse-engineer", meaning reproduce. ~100% of ToS say clearly "do not do this" . and also say "Copyright". but that does not matter to you, does it?

what kind of moral gray areas you are walking in? how is this not clear?

theft and crime was for thousands of years. and the fact that there were horrific multi-million legal cases. this is why we have curts and legal system and ToS and Copyright laws. so people who break the law (or contracts like ToS protected by law) get reprecautions. FAFO.
