Updata: Some behaviour patterns of the cheating accounts.

The only records that almost all of the accounts in these suspicious teams had on kaggle before were commenting a meaningless comment in a random post. (e.g. Thank you! Wonderful idea!) I guess this will turn them from novice to contributor, so they won't be detected as easily!

There should be more suspicious teams in the whole leaderboard. But the contributors teams rank 20~37 now are too wired.
