De-Legro, I'm pretty sure that Aurvandil was a clan that heavily used exploits, not multicheaters.
You are probably thinking of Thulsoma, which was considered by some as a kind of precursor to Aurvandil. They were not the same people, however, nor the same problem. Thulsoma was cracked down upon for their abusing of newbie family wealth issues, namely, while Aurvandil was for multicheating.
Aurvandil was openly talked about because of how obvious it was to every nation facing them, combined with the lengths the person went through to cover his tracks from Devs being able to prove the cheating and act on it. It was a realm that grew huge from nothing, with poor regions but perfect management and mobility, in a time where no one else achieved anything remotely close to that.
The guy spent endless time, however, dealing with everyone and himself, in all places he had tentacles. He namely used his own characters in another realm to justify a war with them.
That was not the first time such a thing happened. Just on Dwi, there was a realm that collasped when a multicheater quit (wasn't even caught). Aquilera or something? Same thing happened to Irombrozia on BT (same guy I think), who also had control in another realm of that continent. I had dealt a lot with his accounts on BT, and never suspected a thing.
Point is, there's no way to know how prevalent cheating is, or what forms it tends to take. We only hear about those who get caught, or those who admit to it. And while the checks might have improved with time, there was a number of people who only admited to it once they tired and quit, so there might have been a lot of others who just never got caught and never told anyone. Some of the cheaters we know of had armies of silent drones. Other cheaters we know of had armies of interactive drones or even characters that occasionally went against each other. But one could hardly use the known cheaters to extrapolate on how the unknown ones behaved.
The whole idea is kind of absurd, though. If having multiple families was deemed to be beneficial, then the proposition should be "let's change the rules so players can play multiple families", not "let's promote cheating!". While still pretty unlikely to result in any change, it'd at least merit consideration.
