Twenty-one extra torrent sites and aggregators are now being blocked in the UK.

Music industry group BPI obtained a High Court order earlier this month, which stipulated that UK ISPs must block their customers' access to the 21 sites, with the ban coming into force from today.

"Music companies are working hard to build a thriving digital music sector in the UK, offering fans great convenience, choice and value, but these efforts are undermined by illegal sites which rip off artists and contribute nothing to Britain’s vibrant music scene. We asked the sites to stop infringing copyright, but unfortunately they did not and we were left with little choice but to apply to the court, where the judge considered the evidence and declared that ISPs should not serve access to them," Geoff Taylor, CEO of BPI, said in a statement.

BPI obtained similar banning orders for four torrent sites — The Pirate Bay, Kat, H33t, and Fenopy — earlier this year, but many users were able to circumvent the block without too much trouble.

According to the BPI, the block has led to a "significant reduction" in use of the sites, though the organisation did not provide any details of how it had decreased.

As of today, the 25 sites blocked in the UK are:
