great! some folks are really taking actions!

i'll write a new post a few days later to try again.

my suggestion:

take advantage of AI:

people everywhere are trying to teach how to classify useful emails from spams using Keras mostly with tensorflow back-end. i think this technology isn't hard to get these days. use that.

then entice a large group of people to mark hams and spams with criteria set beforehand (ham being good posts).

after that, train the neural network for a while, and put it in use to flag spams and upvote the hams.

eventually, spams will always be flagged, and all hams will be put upfront and earn a rain of rewards generated from flagged spam as an encouragement to post new good stuff.

but, i know, good guys still have to compete with each other with bots. i haven't figured out anything for that yet.
