Essentially, yes. UC is not more aggressive *by definition*, but it
certainly has the potential to hit on ham, which is why it is, in some
ways, fundamentally different than the SURBL philosophy. I.e., it is not
a "block list", but more of a "spam sign" list. That's where the divide
exists in many of these black/white list discussions. There seem to be
camps of people that think in terms of one, or the other, but
comparatively few people seem to look at both approaches.

I'm confident, though, that once UC grows to a statistically significant
size, the FP rate will nonetheless be quite low indeed.
