I'd just like to point out a few things about the bogeyman that is the multi. They aren't quite the radioactive menace people think they are. Annoying, yes. Sowers of distrust, sure. But they probably exist in roughly the same proportion as they did when the game had thousands of players. It's just easier to see them now, and their actions have an outsized impact.
Supposing that we need to spend dozens of hours every week (that's probably an accurate estimate) locating and verifying multis in order to create a healthy atmosphere is misguided. It prevents devs from working on useful things. It prevents rulers from focusing on creating international intrigue. It prevents players in the realm from interacting meaningfully. The best advice I can give is to simply ignore the idiots and then watch them get smacked down when they stand up too tall. And they always do. Nobody creates a multi net in pursuit of adequacy. They want to "win".
They can be handled IC, if you have patience and a proper team atmosphere. People understand when something seems fishy. Thalmarkin dealt with it. Others have too. The argument that the judge will get protested out is ludicrous; RE-ELECT THE JUDGE. ELECT ANOTHER JUDGE WHO WILL CONTINUE THE WORK. Complain to the Titans about all those dicks who keep protesting out Judges. The group won't last long.
So, what Alex did was commendable, but it was probably not the best use of his passion. He was hardly even the most diligent among those who regularly ferret out multis. Some of the best at that were, in fact, multis themselves once.
