A few days ago was playing a game of Snooker with this player going by the tag 'miserie' and was taking quite some time to take his moves, then when it was my turn to play the que ball (white) started moving by itself & stopped in a snook position. Instantly realized that there is some hack going on, so I ended the game. 
Don't know how he managed remote access, but he might also do other things on your pc while you are alienated taking your turns. Each turn is 60 seconds, I suggest it gets reduced to minimise risk & ppl be wary!
