Ultimately all it does is serve to make it EASIER for the real cons because they can hide in the chaos and noise while you go after the "pajeet" scammers. Then after all is said and done we are still left with a huge amount of conflict, disagreement, and fraud as well as a lot of innocent users swept up in it. It is counterproductive.
You don't know that "pajeet" scammers aren't part of larger rings of serial scammers. Not doing anything at all is far worse.
You don't see how it increases somebody's profile? Tell me, there are some members here that have done little to no trading here yet have stacks of great ratings. What are the majority of them related to? Right "scam busting". Real or not quite so real, it doesn't make much of a difference to some of them... it all makes them look more valuable, and there is no penalty to being wrong for them.
Trading shouldn't be the only way to build up a positive reputation. I don't think the majority of non-trade green trust comes from scam busting, but it should be encouraged, not discouraged. If people are rewarded for their positive contributions to the forum, its a motivating factor for them.
Of course the system isn't perfect -- nobody ever said that it was. But the forum shouldn't be regarded as a free for all for scammers any more than it presently is.
Your first statement is neither a fact nor an argument. It is at best your opinion. Just more hypothetical waxing poetic about more sky falling rhetoric.
People are free to build their reputation in all kinds of ways. They should not be entitled to abuse a system designed to protect noobs engaging in transactions to make themselves look as if they are trustworthy with funds when all they do is go around stalking users and harassing them with their specific interpretation of the rules while the mob stands by and throws gas on the fire.
Either the trust system ratings are primarily for trade or they aren't. If they aren't then it is just a meaningless joke of a popularity contest that will only serve as cover for con artists to use perpetually to rip people off because they can just keep buying/hacking accounts.
Without trade there is no risk. Without risk there is no trust. Without trust it ceases to be a gauge of who is trustworthy and serves only as a system of nepotism and might making right.
