BitTorrent, VPS and no DMCA

just had found being able to run a torrent seed box (in a medium bandwidth VPS, cheap) without getting DMCA requests, restarting daemon every 240 seconds - new randomized port on each restart. Using Deluge as torrent program and 8 lines of bash script to do the restart job. i forgot the restart script once and, next day, DMCA arrived. didnt bothered to found the optimal value since 240 seconds is ok for my needs. any other experiences? -Virilha
