That's why I use Rapidshare,
Don't be cheap.
dude you suck :P they can see what ypu are downloading un less it is encrypted so unless what you download has passwords on RS I mean ex: you download rar files if no pass protection theyy will knoww and dont forget they can read the file name :D
problem :: ısp monitors your traffic consider is like snort or sniffing if they see stuff like trackkers they mail you or do something like it
solution:: use a secure proxyyy I mean encrypted proxy your ısp wont be able to know what you are doıng :D
