He asked me whether he could demonstrate that the Trust system is broken. I said that he could, though I didn't know exactly what he was planning, and I don't like what he's doing here. Trust isn't the right way to respond to people whose posts you dislike. If I'd have known that he was going to do this, I would have warned him that it would probably result in significant backlash...
I'm happy with the performance of the Trust system here so far. I have a few more default-untrusted negative ratings, but Inaba's default trust score went from ~5 to -261 overnight. (I did not change anything about how the Trust system works for this.)
Yes, it can be gamed and/or manipulated. Tell me what system can't be? The biggest "problem" I see is the retaliatory feedback but very often that very person accrues multiple negatives short term/long term.
