tools in that it does not support active file sharing. While copyright advocates view Xunlei as a P2P tool that facilitates copyright violation, P2P advocates criticize Xunlei as a P2P vampire with much more downloading than uploading. Many pure P2P tools have blocked Xunlei, although this trend weakened after Xunlei began balancing the number of downloads and uploads.
Experience has shown that Xunlei version 0.1.0.0 refuses to upload any data for a torrent that has only two leechers (i.e., when the only seeder is offline). All chinese ISPs limit BitTorrent bandwidth, as a result the chinese users can't upload as the rest of the world (http://wiki.vuze.com/w/Bad_ISPs).
This problem seems to be fading as more and more downloading tools embrace P2SP and bandwidth
becomes cheaper.
