That's right. The problem with SUBJ_ALL_CAPS is that it tends to catch really odd fraud spams, foreign-language spam etc. that the other rules fail to spot; this means that the GA likes it quite a lot, since despite the occasional FP, it reduces FNs enough to make it "worth it". it's hard to avoid this issue. :( --j.
