Jdownloader
I noticed downloading files from Rapidshare generated a tonne of spam e-mails. I contacted Rapidshare, and got the canned "run virus software" response.
I've since moved to downloadcenter.net to much success. It's a pay service. You just copy/paste the URLs into the site, and then download everything from their server. Abetter option (to me) than getting an extra 100 e-mails about enhancement pills, replica watches, 6 pack abs solutions and foreign women wanting to meet me. I was also not chuffed to see my e-mail address being sent, as the sender, to heaven knows how many people.
