A humble suggestion from an equally humble user:

We are having a lot of problems with certain posters, and there is one
common complaint among posts: lack of proof of education in subject
matter and coherency.

So here's the solution: make all users pass an IQ test before posting
rights are given. That way we can keep the "smart" (in the best
determination society currently has to offer) on and the
"not-so-smart" people off.

I would suggest such a test to be of likeness of the one administered
by Mensa, but that would just be cold-hearted.
