As its name indicates, snarXiv is a parody of arXiv. You can test your bogus-title detection skills at snarXiv vs arXiv. I didn’t get over 60-65% myself (after some 15-20 trials); I could detect the really blatant fakes (“Towards some general examples”), but really my performance is only modestly better than a coin-flip. In my own defense, I’m not a physicist, leave alone a high-energy theoretical physicist. How did you do?
