Those images are pretty cool-looking. Does anyone see anything in them that would suggest specific changes to the default trust list? I was trying to look for "islands" of not-default-trusted people that aren't just created by one person, but nothing stood out. I wonder if it'd be good to increase the default depth to 3 -- a lot of the graph isn't trusted by default.
With default Depth 3, pink, purple, dark and light blue are all in DefaultTrust. Ratings from the darkest green people would count towards trust scores. I don't think arbitrarily including another rung of ratings is a good idea because if we think there are problems now, we'll have 20x the problems. No one's trust lists are geared towards that and ratings left in that tier probably weren't left or have been vetted with the intention of being rate altering. From the obscene Depth 11 graph, there are some conclusions we can make and exceptions which would need to be removed.
The pattern you really want to see is like OgNasty or Blazedout419 - its just a shitstorm of lines without its own downstream cloud. They're also centrally located which suggests increased crosslinking. Unique lists (downstream clouds) shouldn't exist because it means they're the only person trusting those users, which by virtue of being trusted would be expected to have multiple vouches. Its not an inherently evil situation but its a bad flag and is a precursor for abuse. SilentSonicBoom has that excessively large cloud of unique followers, as does PsychoticBoy, Sampy, Maidak, Fakhoury, Mars78 and Cryptology. Some of these users are already in DefaultTrust and so the same negative affect is happening to providing others trust score affecting ability. CanaryInTheMine (who sold trust ratings) and Bicknellski (who is circlejerking trust) both have obscenely large trust lists which don't correlate with anyone else. They'd both require their own threads to consider exclusion by a higher tier if not already.
Swapping back to the Depth3 graphs is more useful as we can solely look at those being added to DefaultTrust rather than also those who's trust ratings would also be included. Yifan Hu is the most useful. This highlights the cloud island problem more. There are several members with 20+ unique members behind their trust lists which isn't a great indicator that those trusts are useful. Those individual islands are then going to compound down another tier and be SO easy to abuse / sell accounts into DefaultTrust.
Everyone wants DefaultTrust to expand, but arbitrarily including another rung is not a good idea. The forums struggle to mediate Depth 1-3 rating disputes, nevermind Depth 1-4. There would also be significantly more lobbying as if the guy who trusts the rating won't remove the rating leaver, they'll go up another rung and try again and again. As we've seen over the last few months, not everyone is resilient to lobbying by potentially malicious people and will remove people from their trust rating to stop the posting. I believe the solution is to promote some of those larger names up a tier if they're willing to maintain their lists, and others to fill their places. That means we're self vetting additions rather than adding everyone and hoping we can retrospectively fix those additions.
The depth 11 graph would appear to suggest a promotion of the following promotions, although this is entirely based on a popularity contest from all tiers of users so will need additional checking. It also doesn't include the quality of their trust lists although generally placement can speak to that.
Depth 2 up to 1 (dark blue up to purple):John (John K.) | - I'm not sure low activity is a reason to kick him off. It made sense when he was inactive, but not any more now he is about. |
Vod | - He's trusted by a hell of a lot of people anyway. |
DannyHamilton | |
Mitchel | - He has a symbol in his name and it ruined my graph so maybe not. |
Dabs | - Small downstream cloud but doesn't seem excessive |
Sirius | |
BCB | |
casascius | |
gmaxwell | |
Gavin Andresen | |
Thick as Thieves | |
DeathAndTaxes | |
nanotube | |
Blazedout419 | |
phanastisch | |
SebastianJu | |

dogie | |
Luke-Jr | - Although IIRC he has quite a unique trust list taste |

Depth 3 up to 2 (light blue up to dark blue):Shouldn't have to add anyone manually, they'll get promoted inherently.
