At FotoForensics (before I blocked TOR uploads): TOR was about 3% of traffic, but accounted for >50% of porn uploads and about 80% of child porn uploads.
Today, TOR is about 1% of overall traffic to the site. (I block uploads, but TOR users can still access and view the site.) However, it accounts for about 20% of network attacks.
