Factions and how to prevent abuse

[DreamWeaver]

Well I am looking at the abuse side of things where players, start up a enemy clan and use it as a mole. We have seen this a lot in other versions of the game. The real question is for you the GM, what checks will you put in place to catch this type of abuse? When you have hundreds of positions, your not going to be able to review this kind of stuff, like player X has three clans and their in A,B,C factions and etc. I am just pointing this out now to consider how this abuse can be stopped, making your job easier to catch this stuff if it happens.
