Call me stupid...

But where the hell is the announce URL SumoTorrent? Or is it just a search engine? I have some torrents that are getting traffic but have no idea how to upload to most sites beyond TPB

as i see they don't have a tracker which is just belongs to them, it seems to be they're just indexing the torrents, the site operates as a search engine as you said, so you can upload the torrents to sumotorrents for example with the tpb trackers or with the usual open trackers
