I\'m quite late on this, but back in late August or so, I quit Jan Ryu Mon after noticing a highly suspicious trend of a few of my opponents having the most ridiculous luck, plus one particular guy who had the most ridiculous stats at the top of several leaderboards. I suspect somebody may have discovered some kind of an exploit, perhaps to get the order of the tiles left in the wall before they\'re drawn - a long time ago, Tenhou used to have an exploit that made it possible to do this, though they\'ve since patched it up. This would certainly explain stuff like that riichi + ippatsu menzen + tsumo on a tanki wait I saw.
Then there\'s the possibility that a group of players started trying to collude - on one occasion, I had two opponents who kept calling pon on each other\'s discards, and they had the EXACT SAME AVATAR.
Those I think are the two most plausible explanations, because the third most plausible one I can think of is that the aforementioned suspicious player is Amae Koromo and some attempts to clone her went horribly askew.
