Well, in that case...

We had no system in place to monitor accounts properly. So we built a few tools, and although jagan's account looked suspicious, there was no hard evidence. The players then went all lynch mob on jagan (which I still disagree with, but at least it ended well). So we refined our tools, and jagan looked a bit more suspicious. Then he made our job easier by simply telling me the truth after a long talk.

So, if we use our same tools, and anybody looks as suspicious as jagan, we know to continue digging deeper.

Plenty has changed. The players generally avoid the lynch mob and public accusations of other players, and instead message me privately. We've caught a few dupes that way.

We also created a number of admin tools for monitoring player activity which made verdicts for potential cheaters much quicker to pass.

So basically you guys switched to Verizon and let the NSA handle it. Cool!
