At a previous job, I was downloading daily legal torrent data when IT flagged me. The IT admin, eager to catch me doing something wrong, burst into the room shouting with management in tow. I had to calmly explain the situation, as management assumed all torrenting was illegal and there had been previous legal issues with an intern pirating movies. Fortunately, other colleagues backed me up.
Hey, ages ago, as an intern, I have been flagged for BitTorrent downloads. As it turned out, I was downloading/sharing Ubuntu isos, so things didn't escalate too far, but it was a scary moment.
I left a Linux ISO (possibly Ubuntu) seeding on a lab computer at university, and forgot about it after I'd burned the DVD. You can see this was a while ago.
A month later an IT admin came to ask what I might be doing with port 6881. Once I remembered, we went to the tracker's website and saw "imperial.ac.uk" had the top position for seeding, by far.
Fortunately, it was the nice way — that university is one of the backbone nodes of the UK academic network, so the bandwidth use was pretty much irrelevant.
