I created a modified version of LimeWire, that allows you to block vendors from connecting to you. I also added password protection for the filtering options and an option called ALLOW_ONLY_LIMEWIRE_UPLOADS in the limewire.props file. It is deactivated by default but if you activate it you will only answer upload requests from LimeWire hosts.

The file is called:
LimeWireKrieger_Modified_NoAds_WindowsLinuxMacOSX. zip and is now available on gnutella.

- Err, and you will need LimeWire to download it.
