When, in late February, Pakistan's Telecommunications Authority (PTA) issued a call for proposals on a large scale internet filtering system to allow for the blocking of up to 50 million URLs...Pakistani rights activists were more than a little peeved...As sure as the PTA will continue their attempts to censor, the efforts of groups like Bytes for All and Bolo Bhi show no signs of abating. And with the support of international groups - which help by raising their voices to a fever pitch - they may just win.
