Leech

[Tanya Shivari]

Someone who calls themselves a friend but they only use you until someone better comes along to feed off.

[Becky]

Originally meaning to be able to download without uploading. FPT sites many years ago would often have ratios where people would get a certain amount of downloadable bytes for every byte they uploaded. Sites that did not have ratios were said to be leech sites because you could download all you wanted without having to upload. Now a days most FTP sites are leech anyway. The term now more refers to any individual who is often into the piracy scene and does nothing but download files for cracked versions of software, movies, music and so on. They do not share what they have downloaded and dont provide help to others looking for certain files.

To solely download from a peer-to-peer network, without any intent and/or capability to redistribute files accordingly. This lack of sharing is often due to inanely selfish motives, but is occasionally the product of a implausibly slow upstream transfer rate or lack of content to share. Possesses highly negative connotations.
