Examples of this are neighbors who will intentionally attach to their neighbors wireless network and receive their Internet access through them. This sort of leeching has been the topic of several legal debates lately.
• Direct Linking - Direct Linking is a form of bandwidth leeching in which the leech places an unauthorized linked objects, often images, from one web page onto another.
• P2P Leeching - Often found in the BitTorrent community, a P2P leech will download the data offered, and not share their upload with the rest of the community to benefit the entire swarm.

In related terms with BitTorrent, a leech is also simply someone who does not possess the entire file that is being offered. Therefore, all BitTorrent downloaders are leechers and once they have the completed file, should they choose to leave their BitTorrent client connected, they then graduate to a seeder. The negative sense of this term comes to play when the downloader disconnects as soon as they are done downloading the file.
