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.

We basically run a pagerank-like algorithm over the trust graph.

I figured it was something like that.
This will tie into something darth brought up, is the algorithm non-linear in such a way as to discourage trying to game it by splitting your activity across multiple accounts?
my understanding of Zaprank is influenced by
a. how many stackers zap you
b. how high trusted they are
c. how big the amount they zapped
It seems like we must also have something like a global trust score.
there is, once you log out. 👀
reply
how high trusted they are
That's the crux of my question. How trusted they are by who?

That's sort of what inspired these questions. @grayruby was making fun of me because my zap of his fun fact had basically no effect on it's ranking.
I wasn't thinking about outlawed (or just net downzapped) content. That would make sense.
