I never really trust anyone who offers to hold onto other's money when they're not qualified to and more often than not it does go sour when they do and that's why this is such a big issue that makes me intrinsically distrust people when they do it.
For what it's worth, I understand your position on this and respect it--and I know why you left that neg for mdayonliner.
In real life, I generally tend to look for the best side of people, though I'm not stupid enough to take everything people say and do at face value. And yes, I've been fooled many times before and expect I'll be fooled again. I try to take a much more skeptical approach on bitcointalk, where it seems like the proportion of scammers here is orders of magnitude greater than it is IRL.
Every man has his price, as the old saying goes. Whether or not that's true, well that's a whole other discussion.
I suspect it's true for most people, unfortunately. We've all seen seemingly good members go bad on bitcointalk when the potential to run away with someone's funds presents itself, and I'm pretty sure we've also seen this happen in business, politics, and a lot of other situations that have nothing to do with this forum.
As for me, I'm going to try to be more vigilant, diligent, and fair when evaluating whether someone deserves a neg--and I'll do my best to not be so naive about members and the image they try to present to the forum. I'm not comfortable when mistakes come back to bite me in the ass because I relied on someone else's blockchain detective work and handed out undeserved negs because of that.
