I wasn't even close to looking for this but saw this post so I will chime in. First, women cheat too. As matter of fact on a percentage bases I have found women are actually more likely to cheat. Second, isn't it pretty common for people to try do this in various ways, to cheat? Some being flagged by SMAC I assume.
I had a buddy who used a sv_cheats "bypass" and then ran a "wall hack" in TF2 for months without ever getting detected. But this wasn't yesterday
