From EMule Wiki
Applejuice is a eMule leecher mod which has at least the following bad features:
- Doesn't provide sources, which violates the GPL. Might contain bad software, but it's impossible to tell without sources. Distributing this mod is illegal.
- Uploads to applejuice clients first and then has little upload to other clients.
- Thief nicks
- Make browsers show ads. With the needed extension, show ads for an expensive Usenet server too.
