The only idea I have is that you start threads at reddit teaching subs. When I post a any "help me" question at that site - I often post in 2 (if not 3) related subs. So many assholes will insta downvote. It doesn't matter how long/short/well-phrased your question is. It's how the site works.

Tragically - American teachers are far too familiar with dilemmas like yours.
