A researcher wanted to do a meta review evaluation of his research interest and came up with hundreds of papers when he only expected around 60.  Most of them were likely fabricated from paper mills.  This sounds pretty sad.
The ID perps almost never publish their junk in real journals, but it sounds like there are a lot of journals out there that would be happy to publish the IDiotic junk.
