Because Movistar holds exclusive broadcasting rights for La Liga in Spain, AceStream links are frequently targeted by copyright enforcement. This means IDs that worked last week are likely blocked today. To find IDs, users typically look toward these community hubs:

Because AceStream relies on BitTorrent technology, your IP address is visible to other peers in the network network. Anti-piracy organisations can monitor these swarms to identify users and send copyright infringement notices to their ISPs.

Each viewer acts as both a client and a server, uploading data to others while downloading [2].

To watch Movistar La Liga via AceStream, you need two things: the AceStream software and a Content ID (a long string of alphanumeric characters).
