Reputation System Fights P2P Junk

yeejiun writes "Many of the files that are shared on p2p networks tend to be junk. Organizations such as the RIAA and music labels regularly pollute these networks with nonsense files masquerading as real music/video files. These junk files make it difficult for users to find what they want on such p2p networks. Some researchers at Cornell University have developed a reputation system called Credence, that works on the Gnutella network, allowing users to tell the good files from the bad ones."

buddy, i did read it. let's say i am the RIAA, i pay a kid to vote on tons of files to gain a high reputation level. i record and duplicate that process and create 100,000 user accounts that all have high reputations automatically. now i upload a fake file and give it 100,000 thumbs up votes with my clone army. now because the thumb's up are in the majority, the thumb's down votes will actually result in LOWERING the reputation of the people voting correctly and RAISING the reputation of the people spamming the system. ok, so you ban all those users. ok, now the RIAA runs their user account creation script and has another 100,000 users ready with full reputation in minutes. if you put a delay on how fast users can get reputation then they'll just constantly be creating large sums of users. add some text image verification during user creation? i'll pay someone $10 to type in the text and automate it so i can get 3600 users an hour. do you think you can keep up getting 3600 new REAL users an hour to stop me? i doubt it. YOU CAN NOT run an honest voting system unless every vote can be linked with a unique human. without "barcoding" our nation we can't get anything truly intelligent done.

so how about instead of me reading the fucking article, you sit back and think a few fucking thoughts of logic. TAFFTOL. TAFFTOL.

i understand exactly what it is. if you value someone who votes like you, and we assume you vote perfect, then you will highly respect the vote of someone just like you. so the RIAA creates tons of users that vote perfect. this can be automated and can not be stopped. any sollution to stop creation of fake accounts is just another layer idiocy.

block certain IPs? ok well i'll call up a trojan author and get my account creation program put in his next virus.

require valid email addresses? come on, if this was possible we wouldn't have spam.

if the RIAA is willing to pollute the FILES, then OF COURSE they are willing to pollute the user base, and it is trivial for them to do so.

this is like putting a lock on your screen door after a robber broke the window next door. if he's willing to push through the screen he can still get in. dumb dumb dumb. and you idiots responding are even worse. no, it makes sense, i only trust people that think like me... isn't that how the nazis worked?
