Includes knowing to use bittorrent being aware of how this changes your legal status in the jurisdiction you are living in?
I abstained from using it for copyrighted material (but used it e.g. for Debian downloads) as in Germany there is a fine legal distinction between downloading material available online for personal use and providing material to others (which you automatically do when using bittorrent).
But I don't know about the current state and if anyone still tries to track this and starts lawsuits.
