I'm going to verify that I'm human, go through the cloudfare BS and proceed to agree with yahoo62278  on this except that I don't think members (at least not DT members hopefully) exclude people from their trust lists because of simple disagreements.  I've always understood that the ~ was supposed to be used for members whose feedbacks are deemed to be wrongly-given.  Theymos gave some guidance on that a few years back if I'm not mistaken.

In any case, unless you're on DT or are a contender to be I wouldn't worry about exclusions--but that's just me.  The trust system is so complicated and misunderstood and, in my long-held opinion, broken beyond repair.

Yahoo62278, I'm actually kind of surprised you're asking the questions you posed in the OP since you've been a member here long enough to know that people are going to do whatever they want as far as leaving negatives and neutrals regardless of how many threads are devoted to discussing trust system etiquette or even what Theymos suggests.  Trust isn't moderated and you know that.  

If it comes down to a DT issue, then that's a different story.  Other DT members will (hopefully) ~ whatever DT member is making a habit out of leaving inaccurate feedback.  Jesus, I even excluded Vod from my trust list prior to his departure, something I never thought I'd do.  My suggestion is to meditate, take a chill pill, or whatever and just let the system operate as it always has--because I don't think it'll do anything but that and hence it's in the hands of the community as a whole.

Wavy gravy, man.  Smoke 'em if you got 'em.
