Most people buying Crypto are uninformed. They have no idea that Dash is a total scam.
(Instamine by developers, NOT anonymous as claimed, etc)
They are just trying to make a few dollars on whatever coin is hot at the moment.
The rest don't care.
As long as they can make money trading Dash on Poloniex they are happy.
Its the Wild West out here. TRUST NO ONE.
This includes someone with a PPL rating. Its a cool idea but it may lead people to get scammed if not implemented correctly.
Giving someone a trust rating can be dangerous. How many people have been scammed on these forums from a "trusted" member after an account was sold or stolen?
I agree with everything you said, but I think the PPL add rating can help add a significant amount of context. If someone has years of positive PPL feedback, they're probably not going to throw that away on a <1 BTC transaction which is where the vast bulk of these will be taking place.
But yes, a 100 BTC transaction, for example, you should never trust anyone.
