"Hey, I proved the Collatz Conjecture!", proompter says one day before severe bugs disclosed in theorem provers

⚠️⚠️[IMPORTANT EDIT: it was later clarified that the person who originally posted the proof was already aware that it was buggy, and chose not to be clear about this up front, as a humorous way to file a bug. It's pretty clear from the discussion threads that plenty of qualified people did not immediately realize it was meant to be a bug report.]⚠️⚠️
