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.
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.
