i2hub is a Direct Connect (peer-to-peer) hub that tracks users on Internet2-connected colleges, thus wasting lots of grant money and effort by researches along with the inevitable bandwidth hogging.
They decided to snarf bandwidth-utilization graphs from our web site, so I set up mod_rewrite such that any hits with a referer from either of those web sites would NOT get the pretty graph, but rather this image.
One of the two links above has removed the WPI graph, but the second one has not yet.
Is there system smart enough to search the local campus for files before looking on other campuses? If so, they may be saving bandwidth through intelligent server selection, considering that around 85% of bytes transferred in P2P applications are already elsewhere on campus.

And were on the news and stuff and will get resoundingly spanked by all of their colleges, I'm sure.

Either way, our routers are set up to filter most of the detectable packets for this particular service anyway, rendering it unusable.
