Mad chess players

Your opponent is probably just getting paranoid because he/she lost and is frustrated. Just tell him/her that if you're cheating, you got ripped off on the chess program you're supposedly playing with because your rating isn't very good (ie, your chess program plays at 1500-level). Of course some people may cheat some of the time (or seldom), while not cheating most of the time, so it is possible to have a lower rating and still be cheating.
I wont reveal name but of course you could find out by looking at games. Calls me a program-user/cheater tells me to go cheat someone else. Here is the game.
