Digital locker service FileSonic has gone offline and restricted its members to access other’s uploads following claims that it was hosting copyrighted content.

FileSonic started imposing restrictions on its users after MegaUpload was raided by the FBI earlier this year.

Megaupload’s shutdown has also made many of the Internet’s cyberlocker services to change their business models to avert similar allegations.

Earlier Miami-based Flava Works had accused the website that it is making profit from piracy by inducing its members to infringe copyrighted materials.

In a bid to stay out of the copyright infringement, Filesonic had partnered with anti-piracy firm Vobile in December 2011, but in February 2012, the International Intellectual Property Alliance (IIPA) reported Filesonic to the United States Trade Representative (USTR).

According to reports, Filesonic has been completely inaccessible through its .com domain following alterations to its DNS settings, acccording to TorrentFreak report.

TorrentFreak editor Ernesto Van Der Sar was quoted by BBC as saying, "It’s becoming more difficult for file-sharing sites to operate without getting into trouble both from the authorities and also lawsuits from copyright owners."

"Anyone looking to find a particular pirated blockbuster movie or other popular file online can still do so, but some of the e-books and more obscure content are becoming harder to find, and reward programs – offering uploaders cash for their activity – are less common," Sar said.

In July 2012, adult entertainment firm Flava Works has sued Filesonic claiming it as ‘websites that copy, store, distribute, display, profit from unauthorized copyrighted materials, and/or induce and assist others to infringe copyrighted materials.’

According to Google’s Transparency Report, the search giant alone had received requests from UK based music publishers, including Warner Bros, NBC Universal, Microsoft and the BPI, to discard about 151,000 search result links to suspected pirated material hosted by FileSonic.
