I agree that going form a trust score of +81 to +87 doesn't seem like a huge difference, and it's unlikely sway the decision of someone looking to do business with OGN, but your statement begs the question: At what point does it matter? If adding +6 to your trust score through manipulation of the trust system doubles your trust score, would it matter then? What if it added 50%, or just 10%?
I don't have an answer to that 
My old data on Selfscratchers shows much worse cases, and at that time I scratched myself up 4 points. I would update the data, but the Trust changes that happened since then make it a more work than I want to spend on it at the moment.Does +67 (which is what you get after ~OgNasty) to +87 matter?
The +6 boost is just the latest one.
Maybe, it's still not even a third, and at least some of them probably deserve it.The +6 boost is just the latest one.
