This is a dangerous path to enter, even if you mention no other sims. What always happens is the camps divide on the "yes, I know there are hackers" and the "no, no one hacks here" border. Inevitably someone posts a screen or quotes a comment, and the witch hunt is on.
Best to leave this stuff alone on a public forum. If you have definitive, irrefutable proof mail it in by all means. That said, it should be remembered that people are people, and there are probably just as many people trying to cheat here as anywhere else (whatever that means). Best to assume the best in everyone you meet, because life's too short to stress over whether the guy that just killed you is cheating or not.
