Seeing Cheaters/Hackers in PvZ 2 - Arena (Sea-Shooter)

I have been playing the PvZ2 Arena and the same user[REMOVED] keeps popping up as my competitor, and he gets 750,000,000 points within  seconds of starting the battle. I know this is a simulation and not the real person playing, but there is a bug with the points when playing them. 

Thanks!
