I noticed today that 4 guys have beated the previous record on facbook and the best one beat 40 lines in 20sec! Im mostly posting if someone wants to see the replays before they will be deleted.
There always seems to be at least one more cheater to come cloud the leaderboard. Their replays always just look like poor play sped up, heh. You can get a similar effect from watching a cheater's natural replays on 2x or 4x, haha.
I looked at the 40lines leader board once and the person in first place was a girl who cleared 2 lines in 9 seconds (that is not a typo, she only cleared two lines to beat it). That was probably the worst thing I've seen there. The cheaters sort of ruin the game but that happens in a lot of online stuff. Then again my dislike for Facebook tetris leads me to feel Facebook tetris ruins itself more than anything.
^probably not a cheater, just a glitch in the system since the most widely known way of cheating still requires them to clear 40 lines.
