Double-check the bibliography for predatory publishers and journals

Hello,

As mentioned in this discussion, it seems that the well-known pre-print server arXiv is considered predatory.

I like the idea of a built-in list (for well known scams) however:

  1. it would be nice to be able to tune it the list (add or remove entries)
  2. I think that arXiv (and other well known pre-print servers) should not be part of the built-in list. People using articles from such sources are aware of the “risks”.
