Why doesn't it hurt our trust scores?
These would not generally be categorized as "good" posts. My understanding is that "trust" is a measure of our likelihood to zap "good" content.

From the faq
and lose trust by zapping bad content.

but then zapping bad ones is not equal to no one zapping your comments? I think bad content is like the ones got outlawed?
Many of us zap almost every reply we get, varying the amount to reflect quality. Oftentimes, these are comments that no one else zaps. Does that hurt our trust scores?

Roughly: Person A trusts person B according the binomial proportion of their zapping. That is, roughly,
# A agreed with B / (# B zapped - # B agreed with A). (We construct a confidence interval so we can predict with smaller samples what this proportion is likely to be.)So if B is zapping a lot of stuff that A never zaps, A begins to trust B less. But, importantly, we normalize A's trust among everyone they trust, so if A isn't zapping at all for a period of time, and person B continues to zap as does everyone else, A will continue to roughly trust B the same.
When A downzaps things B has zapped,
# A agreed with B roughly becomes # A agreed with B - (10 * # A disagreed with B).Note: this is only a single link in the trust graph. A can never agree with B directly, but still end up trusting B, if A trusts C and D, and C and D trust B.

I think I understand the trust graph concept. How is that converted into our effect on zaprank, though? It seems like we must also have something like a global trust score.
I wasn't thinking about outlawed (or just net downzapped) content. That would make sense.
