1) Addenums(imposures by various houses and factions) can lead to massive purges of scapegoats(typically mid-level scions, low enough that their disposal is not devastating(but it can stall or delay operations within a given area marvelously), but high enough to be satisfying to the accusers)
2) Many can only be reached by the sword of the "law"(again this leads to scapegoats(not only of the previous variety but mannequins/doppelgangers(physically identical and cerebraly symmetrical clones(think of it as throwing your coat, which carries your scent, to distract them)
