we can debate all night on this topic, but really neutral does not mean tagging someone thet you don't like. an example of trust feedback is:
1- positive > you had a successful trade/trades with this guy, you send them money first, they kept their end of the deal and sent the goods > trustful.
2- negative > this person scammed you , by either not sending you the money/goods he promised to, or they arrived in bad shape > can't be trusted
3- neutral > they sent you the money first , you sent them the goods > ( they had no chance to scam you ) but this does not mean they are "trustful" thus a neutral represent that the person has done a successful trade without being in a position of gaining trust hence " ability to scam".
On the trust page it says:
Neutral - Comments. Your rating will not affect this person's trust score.
I am sure Theymos can confirm that this is the initial propose of the trust system. you see people with negative trust " Warning: Trade with extreme caution! ". it does not say "Warning: Interact with extreme caution!
if the trust system was meant to be the way the you think, then why theymos doesn't have it show across all parts of the forum? it is a pretty plain simple answer.
I think the fact that it doesn't show e.g. on local altcoin boards is a bug, not a feature. Some ICO scams like Arbitao have been essentially booted out of the English ANN board but prosper on local boards. But that's a whole different story. Neutral doesn't affect any of that so I'm gonna keep using it for "comments".
