The main threat to your privacy induced by BitTorrent lies in your IP address being stored in the instance's BitTorrent tracker as long as you download or watch the video.
A timestamp (<x id="START_ITALIC_TEXT" ctype="x-i" equiv-text="<i>"/>00:05<x id="CLOSE_ITALIC_TEXT" ctype="x-i" equiv-text="</i>"/> for example) is automatically converted into a link to a part of the video.
