For some reason I don't have a problem, but I always say everything in a super roundabout way.
They made major changes to that system last year and for obvious reasons they don't share how it works.
I suspect it's now based on number of reports weighted by how "reliable" each person's reports are deemed to be. It used to just be straight bayesian scoring with some words being one-tolerance (you must say them twice to get actioned)
