Sorry but no, it would be possibly obvious which it was, and that username is tied to my real life name too clearly.

Summary: our message board was being used to coordinate csam, both the creation and consumption thereof. At first we just edited the posts to point to gore and other shit like that thinking it was just perverts sharing links. But then we realized there were times, dates, addresses/coordinates also being shared, hidden in the board in a way we didn't expect. The site owner immediately turned all information over to law enforcement and nuked the site entirely.
