Having thought about this a bit more, I think that the prevalence of multis is actually very understandable given the current structure of the game. Because of how important estates are, realms need nobles. Estates are more important than soldiers to carry units, IMHO. So a multi that sets up an estate then does basically nothing is actually quite valuable; there is a very high return on cheating. I know that multis have been a problem since long before estates, but I wonder if estates make it worse.
Yet another reason to eagerly await the new estate system...
