I may be misinterpreting your comment, but the massive amounts of data associated with torrents don't actually go through the trackers. The trackers just manage peers while the data goes directly from one user to another.
TPB doesn't even run trackers anymore. My impression is that these servers only serve up magnet links (not even torrent files) and textual descriptions of them.
Provided they spread it out even a little, nothing about that traffic should appear out of the ordinary.
(or at least that's how I understood it)
