I guess mirrors would stay unaffected, because they seem to be up right now. Someone will probably clone their torrents. They might not have been the best quality, but they were always better than YIFI (YTS). I always liked that you could search Rarbg using IMDB numbers. Also, their UI was really pleasing to me, plus, there were many userscripts that extended the functionality of the site. I wounder who will fill up their place, because TPB was always the last resort for me. In the meantime Btdig could be a nice transitory place to find all of their torrents.
