A little over 5,000 users have voted, and those votes affect the forum's trust system for millions of users. Not my idea of good representation. Doubling the threshold for DT2 inclusion isn't going to fix all the abuses from which the trust system suffers, but it'll make it a bit harder to abuse.
Yeah, it's somewhat bad that so many users are potentially blindly trusting the DefaultTrust. However, 5000 users voting isn't actually to bad. I mean there's a common belief with statistics that at the very minimum 1000 should be in the dataset, which we're above at the least. Obviously, the more, the better that goes without saying.
Although, 5000 users including various different users, isn't a terrible representation. It would be interesting to see how those 5000 trust lists differ. You know, if they aren't changed all that much, and only adding a few users to the list, or excluding some, that would could be more of an issue. However, 5000 users on face value alone, doesn't strike me as terrible. I'm actually surprised it's that many to be honest. Not everyone trades on the forum, and not everyone necessarily needs the trust system.
