It is only now that I have viewed this thread, When a member reported about violation of a torrent, mod who take action will go directly to the torrent in question and will click "Send Uploader a message" of that torrent. The system will notify directly the uploader.
The only possible reason (highly improbable but not impossible) that someone have the access to your account and uploading .rar file video (file which we allow with images, comic and yaoi, books and magazine but NOT with videos).
The system deleted all those .rar file hence your upload history has a clean slate
