The issue that José describes is an example of predatory publishing, and like José I was also recently taken in by what seemed to be a genuine journal but turned out to be a predatory publisher.
I don't see a solution to the issue of discrimination against those who cannot pay the publication charges. Unless the journal is produced by a professional organisation as part of their mission, someone has to pay. It is either the reader or the writer. If you have a research grant, you can include the fee in the grant, but unfunded research is much more difficult to find an outlet in an open access journal.
