People have been saying this same thing about the trust system and the DT members in it for years now.  I'm not sure if the rotating system has made things better or worse, but with Lauda gone there do seem to be fewer "cliques" within the DT system.

I hadn't read any of your previous posts, OP, so I'm not sure why YOSHIE and the two others tag-teamed you with neutral and negative feedback, but I don't think any of it is justified.  You might have been too persistent in asking YOSHIE to prove her identity (she wasn't gone all that long and I don't think there's any evidence that the account changed hands), but I don't think that's so offensive that it deserves even a neutral, much less ones harshly-worded as the ones you got. 

Everyone involved here should just take a breath and re-evaluate the importance of the issues at hand, which IMO, are not critical.  I don't think a member who's been gone a few weeks should have to sign a message to prove their identity, and I also don't think someone insisting they do so should get blasted on their trust page.  Get a thicker skin and don't leave what amounts to retaliatory feedback for a trivial issue.
