The IWF's Jennifer Scott said that despite the overall drop, 58 percent of the images online depict graphic images of torture. Among child porn sites that are still active, almost three-quarters of them are selling the images for money.
One striking statistic showed that 850 of the commercially run child porn sites had registered their domains at only 10 registries. IWF chieftain Peter Robbins called this a serious problem.
“The extensive intelligence networks we have with partner hotlines and law enforcement colleagues around the world to support international action are making a real difference but the sophisticated way these websites operate still makes it a highly complex and global challenge,” he said.
The IWF runs a voluntary blacklist in the U.K. Currently 97 percent of British ISPs participate in it. The foundation received about 34,000 reports of child porn last year, down about 3 percent.
