Con Data Leech
Uses way too much background data, while task manager and bittorrent up on the foreground and Bittorrent showing a combined 300kb/s up/download avg on the torrents & TaskManager showed it was actually using an avg of 1000kb/s. There is no way it should be using this amount, and makes one wonder what it's up to.
Con No tracker exchange
Tracker exchange functionality allows peers to exchange information about trackers of a given file. It is another way of ensuring that the file is downloaded from the optimal source. BitTorrent lacks this functionality.
