Yes you are probably correct on the neutral ratings. and yes there is other better moderated forums for Bitcoin and altcoins that is much less biased and centralized than this place. you just have to look around.
From my experience here, a lot of the veteran people are usually scammers who have been previously scammed and are now disgruntled, or lost their butts in Bitcoin from something stupid they did in the past. SO now becasue either all thier projects failed they want to make sure no one elses projects succeed. so they troll. I know a handful of people who seem to have nothing better to do but troll people, attack them, and dig in thier life. But at the end of the day they do not contribute to the crypto community in any way, everything they have tried has failed, and they are just a simple nobody if you take this forum away form them.
For example my negative trust, 1 person on my negative trust does business with me, and he has never lost one satoshi, he has not been scammed, he has multiple accounts with us doing everything he can to try and catch us doing something wrong, the rest, I have never had absolutely any business dealings with them inside or outside of crypto, they all just jumped the banwagon with neg trust becasue they can.
ALL OF WHICH are failures in the crypto community, most of which have scammed others or done some unethical act against others in the crypto community.
The trust rating system here is just another high school popularity contest, and if your not a troll your either red or luckily neutral.
You want to get some red trust? Try opening any kind of good service, the more honest and rewarding your service is the more red your trust gets.
I make it simple, I eliminate any troll from my rating system so i dont see the stupidity reflected in others trust.
