Probably not, but ALL discussion of cheating is forbidden in the general forums. Just join this club and post your question on their forum. I'm not a mod, just wanted to let you know that your thread will probably be locked.

I played a player 1 0 bullet, was obviously winning the game, checkmating him in 3 moves with 18 seconds.
I played my last move, then the game freezes and suddenly I'm clocked and I lose the game. My last move was even written on the note sheet! So I have a screenshot of me making the last move and still losing on time.
