34-year-old Matthew Gene Marquardt is charged with dissemination of child sexual abuse material, possession of pornographic work with a prior conviction and distributing material describing sexual conduct with a child via electronic communication.

The account owner told police he does not initiate conversations with other accounts and reports accounts belonging to adults who solicit his account for sexually explicit material, the complaint says.
