As the title said, what is the best tracker for all foreign movies with its native audio? I'm eager to learn foreign language (Spanish, Russian), I'm thinking to learn those languages using movies (or cartoons like Dora The Explorer (Spanish) and Masha and The Bear (Russian))? Tried to search both of those cartoons on CartoonChaos and VHSTapes but there is no complete sets available. And no, please don't mention apps like DuoLingo, that thing won't work for me.

It's almost impossible to get invitations for Spanish trackers.
The best ones are: HDOlimpo, Puntotorrent, Divteam, xBytesV2, Torrentland, Redbits and ZonaQ.
Other such as pixelados.tv, HDCity, HDSpain, tackeros.tk, TBPlus, hachede are dead.

You can still get some content from emule, public trackers such as DonTorrent, Telegram and websites such as descargasdd.
