That’s strange. How do they stay in business? Unless they are really just “blogs” where anyone can “publish” anything without any editorial/editing/layout.
OTOH, I think that submission fees will reduce duplicate publication, since it’s more expensive to say the same thing twice.
Finally, I wonder why authors self-duplicate. Are tenure and advancement committees so lazy that they do not even look at the papers submitted for promotion? There’s an iceberg of issues here…
