I just got a F.P. using one of the SARE rulesets, looks like the SARE_SUB_PENIS_OB rule might need some tweaking. Seems like it fired from the word pennies:
Yep.. it's crap like that that makes me staunchly refuse to use .? as a gapping character..
It's really odd that this rule has an antidrug obfu style section AND a .? section.. I'd suggest splitting them up. This way the exemption words like pennies pencils, etc can all be handled only for the .? based rule.. the antidrug style obfu rule uses [\W_]? as a gap, and won't suffer from FPs on words like that, but it also won't catch anything obfuscated with extra-letter stuffing..
