Tuokin on vanhentunutta tietoa, että pitäisi erikseen asentaa vertaisverkko-ohjelma. No toki se yleensä asennetaan, mutta esim. tuossa Javascriptillä toimiva torrent-clientti. Klikkaa ja ala jakamaan tiedostoa! :) https://btorrent.xyz/#6a9759bffd5c0af65319979fb7832189f4f3c35d
It's meant for browser based bittorrent clients like webtorrent, btorrent.xyz, whatever some old addons for firefox like Torrent Tornado ... etc. So if the announce is going from the browser to the tracker, it's not likely to be allowed on most private trackers.
uTorrent, BiglyBT/Vuze, Deluge, rtorrent ...etc got web clients running on the browser like rutorrent for rtorrent. The announce does NOT go from the browser to the tracker. The browser UI is just an interface using the browser, the engine of the main app runs on the machine so they are not included in what I mentioned above.
