those users are using a lot of bandwidth and the piracy forms a handy excuse.

Or they could improve their network for torrenting like some Indian ISPs did in the past

Several Internet providers in India have found a clever way to reduce the load BitTorrent transfers put on their network, [...] They've teamed up with Torbox.net which offers a fully fledged torrent search engine that connects users to 'local' peers to guarantee maximum download speeds.

Some [ISPs] have had their own custom ‘caching’ setups but increasingly they are teaming up with the torrent search engine Torbox.

Torbox links them to peers in the local network, which means that the traffic is free for the ISP.

Most people who visit Torbox will see a notice that their ISP doesn’t have a peering agreement. However, for those who have a supporting ISP the torrent site returns search results ordering torrents based on the proximity of downloaders.

TorrentFreak spoke with EBS director Victor Francess, who says that with this setup most torrent data is served from within the ISP’s own network.

“It all creates a very powerful user experience, so in fact just about 10-20% of all torrent traffic comes from the upstream and everything else is local,” Francess says.
