As a responsible Clan Leader I pay attention to the people that are taking points form my clan. Well in the process I noticed a few people that wouldn't normally hit my clan. So I check to see if I was hit by them, nope. I checked to see who was on their Fightlist, none of my clan. So I checked to see if anyone from my clan was hitting and losing to them, still the answer is no.
So I have to ask how is it that they are taking points from my Clan?
