I was doing a workshop there called \"Dirty tricks for image classification\" (video should be available soon).\n\nAmong several tricks I shared with the participants was googling file names from the test set. Guess what? It also works for text classification :)\n\nTry to google *00c660c58101eafe25e9*. There is going to be only one result: this link https://pastebin.com/KeVgnB6L which looks very much like a submission. To save your attempts, it scores 0.699 on LB. It was uploaded on NOV 16TH, 2018 - the exact same date when someone called **lcch** got the same result (see [raw data][1]).\n\nAnother day, another \"leak\"... another valuable lesson for @lcch135616 ;)\n\n  [1]: https://www.kaggle.com/c/10737/publicleaderboarddata.zip",
