- Trust should be shown everywhere
Not really. It would have a negative influence on how users perceive others. In a perfect world users would judge a user on what they have written, but that really isn't the case. We aren't all rational, and users jump to conclusions, and immediately discredit anyone with negative trust. Regarding the signature campaigns, then maybe. Maybe it would be best if we just disallowed them. It would be a pity though.
Let's be honest here for a second: This whole forum has a slightly negative influence. A place to scam, a place to spam, a place for everything that is "grey" or simply overlooked. Yes, there are some spots between all that dirt but they are getting smaller. Being labeled all the time, might force people to think first. I know it's not perfect as with all the ongoing personal bitchfights the view is wrecked unless you customize your trust view.
