I noticed the negative feedback from 2 DT-accounts yesterday. I don't think I've seen something like this before, and I don't think this is how the Trust system is supposed to be used. One person should not give someone positive or negative feedback from more than one account, as it leads to
2 positive or
-2 negative on the user's profile.
A simple solution would be if hilariousandco uses hilariousetc for all feedbacks on your account.
This person is well know for having deleted my posts on a whim whenever it suits themselves, as evidenced in their having recently deleted my posts in the bitcointalk interview thread
Can you show the post? (Or I can dig deeper by myself later)
In general, complaints about moderation should be made in Meta. I've seen theymos restore deleted posts based on this (that happened in Politics & Society).
