Dotcom told Ars that Megaupload’s relatively modest share of infringing URLs was significant because his site was the world’s largest locker site in 2011. “All the other file hosters in this list were significantly smaller than Megaupload,” he told us. Megaupload had “1.5 terabits of bandwidth utilization” before it was shut down. The next largest, RapidShare, had only about 800 gigabits, he claimed.
“If the largest file hoster in the world does not represent a significant percentage of infringing URL‘s found by IFPI, this can only lead to one conclusion,” Dotcom told us. “Megaupload was very effective in taking infringing links down.”
