As theymos noted, the red trust should be strictly for scammy behaviour.
The people who like to use their feedback as a weapon or to get one over on people because they have some sort of beef with them aren't going to care about leaving neutrals and it's those that are causing most of the issues, but of course the problem is also 'scammy behaviour' is completely subjective. Some people think certain behaviour is scammy or shady whilst others don't. If a stranger knocks on my door and asks to borrow money from me but promises to pay it back at a later date I would likely find that person very untrustworthy. I think that would be pretty shady behaviour here too and many people leave negative for that and some don't. Sure, they might return at a later date to pay it back but that's probably less likely. Whether you leave a negative, neutral or take no action is up to you, but there are of course many times when a neutral feedback may be more appropriate but sometimes not leaving the negative also lets scams happen. I remember a few times where I've given people the benefit of the doubt and left a neutral only for them to go on to scam and I should have just gone with my gut instinct.
Two examples:
Some people think trying to escrow with no previous experience is very shady. Others don't or don't care. The neutral may or may not have been more appropriate but it obviously didn't stop him from scamming. I think every person who I left negative or neutral feedback for trying to escrow went on to either try scam or was successful in doing so, with the exception of mdayonliner. Had anyone sent him $100k to hold on to as an escrow I'm not sure whether he would have stuck around for long after but of course that is something we'll never know, but add that to the fact that his bread and butter prior to this forum was promoting and partaking in ponzis I think the negative feedback was just either way.
Here's another user where I caught someone actively trying to cheat a giveaway:
In my opinion very untrustworthy behaviour but I left a neutral. It was then later found out that he was connected to multiple scammers and a farming ring.
There's also issues like do you trust a liar? Do you trust someone who behaves like a petulant child or a psychopath? Probably not. Do those sorts of people deserve negative or neutral feedback? You can argue either way. You might find them untrustworthy but they could be an honest nutter. Someone who repeatedly tells lies obviously can't be trusted but they might not be a scammer.
This post is taking on some tiny sample of anecdotal experiences and making wide ranging and broad strokes assumptions, speculations and guesses.
What that post says is. We will create such subjectivity and broad ranging reasons to give red trust that it has obvious implications for free speech and also opens up DT to corruption and payment for red removal. All to protect the very most stupid and greedy. Yeah like most people will go to escrows with no history of being escrows or lend a stranger money over internet? Perhaps we need to stamp people with red trust on their foreheads in real life? this assumes we need to destroy the board, leave DT open to corruption and power to crush free speech to save the dumbest and greediest people here? NO.
The only people fighting the implementation of "proof of scam" or STRONG case of scam are those that want to continue to have the power to influence others free speech and game the system for their own personal reasons.
Behaves like a petulant child or psychopath (would require professional diagnosis)? this bullshit reason it transparent. Anyone who says something I do not like or agree with is petulant or psychotic. NO SORRY, prove they are a scammer, or have tried to scam people in financial terms or you don't get to spoil their account with a scam tag.
Most arguments will end with one party saying that person behaves like a petulant child or they are crazy if they do not see things my way. Just wants a license to give red to anyone for their own personal reasons.
You think they are petulant, disagreeable, annoying, don't see everything the same way as you do. Then leave a neutral and explain your case there. That does not give you license to give them a scammers tag.
This subjectivity is the root cause for all of the arguments and infighting. It also allows red trust to be used to facilitate scams and scammers.
