I should check if there's any existing platform or service in Japan that uses these terms. A quick search in Japanese might help. But since I can't perform actual searches, I'll proceed with what I know. "Kateikyoushi netori" might be a term used in some websites or forums where people share experiences about home teachers, possibly in a negative context, like being "taken advantage of" in educational services, and "houkoku best" could be the best reports or guides about avoiding scams or finding the best tutors.
