This is an on going issue and we all here about. However, Australia ISP looks liek it is trying filtering.
http://www.itnews.com.au/News/81630,child-porn-filters-to-cut-aussie-broadband-speeds.aspxThe study was conducted by the Australian Communications and Media Authority to demonstrate advances in Internet content filtering technologies.
In a statement provided to iTnews, the Department of Broadband, Communications and the Digital Economy effectively confirmed that the scope of the study limits useful outcomes of the report.
“The ACMA report is based on a laboratory trial of ISP filtering technologies, within a network that would be used by a small ISP,” the spokesperson said.
“It is therefore necessary that the Government proceed with a real world live pilot to test how these filtering products work with ISPs of different sizes and network configurations.”
Department and industry have expressed opposing concerns that preliminary findings on the degradation of broadband network speeds caused by the content filters may be inflated, or underestimated, respectively.
Preliminary results from the ACMA study showed that five of the six filters tested degraded Internet throughput speeds by between 22 percent and 75 percent, or more.
Let's see how more tests go.
