That might be your opinion, however your account was created today, and you have two posts, so your opinion is worthless. (your motivations are transparent). You can present an argument as to why your opinion is right, or you can shut up.

When you add a person to your trust list, you are vouching for their integrity, and obviously trust ratings. In order to do this, you must have somehow gotten to know this person, and have observed their behavior. This is fairly easy for moderators and admins because this is closely aligned with their normal job duties as a moderator, hence why (in part) the moderators among those trusted directly by DefaultTrust have few people on their trust lists who have given them positive trust ratings. Those who are not moderators, generally must interact with those they add to their trust lists directly in order to properly evaluate if it is appropriate to do so - one of the easiest ways to be able to make this evaluation is to trade with the person under competitive terms (and/or otherwise collaborate with the person), which will often result in positive trust being exchanged, especially after multiple transactions, so it should be expected for non-moderators to have positive trust from those on their trust list.

If you are a moderator and have not traded with many people on your trust list, or otherwise interacted with them, then there is a good chance you are adding a bunch of strangers to your trust list.
