The trust system has evolved to become much more than that, as you well know.
When you post a negative rating for someone you're confirming that
You think that trading with this person is high-risk.
(emphasis mine)
You're free to think the above but
I think that any reasonable person would conclude by looking at TECSHARE's trading history that
trading with him is not high-risk. Debating politics with him might carry a high risk of being trolled but that doesn't call for a red rating.
Therefore your rating is unreasonable, therefore ~ and yes, I'll consider the same for Vod.
On the other hand, posting a positive rating for someone means that
You think that this person is unlikely to scam anyone.
Which is exactly what I think and what other positive counterers (not a word, don't care) think so those are perfectly valid.
