Soundclick Plays/Views Increaser

Need a coder to figure out how sound click dot com is calculating their music charts on the backend, its based on views but they are somehow able to detect all "Views increasers" and ignore all artificial hits. The views increasers do increase the plays actual numbers but if those plays don't follow their "Unknown" method of detection, they don't raise your songs position in the charts. Here are some known facts: 1- each MP3 play needs to be from a unique IP. 2- Each IP is only counted towards 1 play. (Duplicate plays are discounted) 3- Charts are calculated at midnight (GMT -5). 4- Downloads per unique IP are also counted towards the charts. 5- Plays from "External-outside of the site" users have less weight then users who play within the site. They may be using REFERRER or FLASH [login to view URL] they may be basing it on the amount of time the MP3 is played. Coder will be provided with an account for daily testing, coder will need a source of free or private proxies for such testing. I expect coder to provide "recreate-able proof" of his/her findings and document a solution. This will take the coder a few days of experimenting as you have to wait until around 1am (gmt -5) to see if the tested song has raised in the charts. There are several users on sound click currently cheating by artificially inflating their hits and staying in the #1 spot for weeks at a time, so it certainly can be done.
