Right, will arXiv implement such filters? Same question for other green or gold OA platforms. We all know about Elsevier, but if I put my paranoid hat then for gold OA this is even more perverse, will they try to kill green OA (not that I believe in this failed classification which separates between green "repositories" for archiving and gold publication platforms). Anyway arXiv is a monument which has to be protected from this madness.
