We have so far confirmed that Peter Bright uses the username "DrPizza" for his accounts on twitter, reddit, and arstechnica - dating all the way back to 1999.

Keep searching for users named DrPizza on other websites/platforms. He probably has more accounts in various places on the web. It's important that we keep digging on this guy and the people he associates with online because he seems to have tight connections to pedo inside-circles going back many years.
