of course the site wouldn't run at all, because your making several connections to it, as i've seen in previous versions of WCS where the TCP was a weak striking hole to lock/freeze/instantly force someones wcs to completey close without notice.
And to continue on what some of the other people have been sayin in this thread...
Running a "b/w leeching tool" will not make a difference on mx pay sites .. why ?
Because think about it, if they can spend houndreds, maybe even thousands on advertisement, and find ways to get themselves number 1 on google search when you type in "winmx" in google. Don't you think they have money to support the amount of Attacks, B/w leaching, BotNets, Dos Attacks, ETC ?
I agree that these paysites are screwed. and shud be taken down. But why waste your time tryint to kick a horse down with your bare feet.
These paysites have Dedicated Servers that most likely have TB's and TB's of b/w transfer per month, it's not going to happen that you will shut all of them down, (if you even shut 1 down i'll be surprised).
Another thing is... James... a tool like what you showed me wouldn't even work on a winmx paysite. They run very very very very very good servers, You couldn't even budge such a server to go offline.
