Exactly!
Nevertheless, it's hard for newbies to investigate projects themselves and identify exactly which ones are scam, which ones are un-scam.
The problem [serious one] occur when they got help from other forum users, DT members (who are more professional), with warning messages:
"Scam project! Stay away from it, and stop supporting it!".If, after that, they keep supportin scam projects, and ignore all warning messages, they should be tagged red.
It's the final destination for them.
I disagree, we all have to take responsibility for our actions and this includes researching schemes before promoting them in exchange for payment.
"But I didn't know they were a scam" usually is more accurately written as "I didn't care if they were a scam, I just wanted the money."
I think that excuses for newbie status goes more towards NOT knowing some of the players rather than inabilities to spot a scam or inabilities to recognize facts or employ logic.
We should not assume that newbies are babes in the woods or that that they are 12 year olds. There is a certain amount of responsibility that each of us has, whether newbie or not, and each of us has to perform a decent amount of due diligence (as also mentioned by tmfp above) and use both facts and logic without engaging in too much risk and putting on too many blinders with hopium.
The trust system merely is going to give one additional tool to still take with a grain of salt, but could help newbies or anyone else to weigh the various factors and risks with an additional data point.
