MILPITAS, Calif. - The owner of adult website AmateurAction.net has been indicted by a California grand jury on charges related to the distribution of obscene material.

Robert Alan Thomas, 52, of Milpitas, Calif., was charged Wednesday in U.S. District Court for the Northern District of California in San Jose with three counts of mailing obscene materials and one count of engaging in the business of selling or transferring obscene matter.

According to court documents, Thomas mailed two allegedly obscene DVDs to a person in Washington, D.C., in December 2006.

AmateurAction.net offers a selection of $3.99 adult DVDs featuring extreme content such as pissing, fisting, BDSM and "extreme insertions," according to the site.

The Justice Department is seeking the forfeiture of assets earned through the site, including all property used to commit the offenses. Thomas faces a maximum penalty of five years in prison on each of the four counts if convicted.
