Unstarring it is an interesting choice, if they did that. That means that whomever is still leeching it while at work, etc, might have the 38 gigs of a broken download affect their ratio, though the torrent they clicked on was for a working download that does not affect their ratio.
The uploader self-reported it. It won’t affect ratios: 1. because it was freeleech, 2. because once deleted the tracker no longer collects the peer information. No one had completed it to 100%, but some got to 98% or something (I suspect this was part of the uploader’s problem was that his file had somehow become corrupted).
