After Twinblade, we were able to use the traces he had left in the DB to build some better semi-automated cheater-checking tools. This led to us catching a lot more multis over the following period than we had been able to before.
Since then, we have added a few more pieces of data to the list of what we log (nothing personally identifiable; for that, we'd have to actually ask, and trust that it's accurate!). Once we get some more time, this will let us enhance and refine the aforementioned semi-automated cheater-checking tools.
At this point, it would be very difficult for someone running a multi group the size of Twinblade's to run under the radar without it essentially being a full-time job for him.
