I agree with you that your post in that reference, does not seem to rise to the level of red trust in terms of liar or disinformation expert...

If I were to negative trust you, then I would likely tag you for shilling, pumping PMs, some of your bullshit racial comments or something like that.... and maybe your pumping of certain off topic BTC themes and then not backing up your shit stirring nonsense...  ... so perhaps, the problem with the negative trust could be with the reference rather than the fact that V8 negative trusted you. 

 I do believe that best practice for red trust is to provide some kind of decent substantiating reference... it is not absolutely necessary, but it is preferred to put a reference. 

So, in my personal opinion, there are still likely decent references out there for the point(s) that V8 was attempting to make in his red trust rationale, so perhaps V8 just used a bad reference?  I am not sure. 

Even though I would use a different referenced example, V8 has discretion about what reference he believes substantiates his negative trust decision... and from my seeing your posts, over the years, the overall decision to red trust you does not seem unreasonable - even if V8 seemed to have picked a less than stellar example of his point(s).
