Honestly, why the hell would you use Rapidshare?
Torrents may be a little less reliable, but they don't put you through that shit, and if you're on a private torrent, you're fine.
As for http layer piracy, I go through megaupload for my stuff... 3 letter captcha with a gradient, so it's perfectly legible to human eyes.
However, if you're adamant on using RapidShare, hope on over to
Warez-BB.org :: Index and go to the link-heaven or off-topic sections... People are always giving away hacked RapidShare accounts in exchange for services.
