OP, you're up against the fundamental nature of forums on the Internet.
They are a big melting pot- academics, engineers, students, techs, noobs, trolls, jerks, idiots etc. Anyone can post.
Unfortunately it's easy for a troll to derail a thread. Crowdsourcing a design is pretty much impossible, to my lament.
To keep quality up, social media have tried adding upvotes and karma. But then people collect karma and upvotes, as some form of currency.
Or we'd have to prove our credentials and be ranked somehow, as members. I haven't seen the best fix.
Until then, the signal to noise ratio can move around...
