Miami-based lawyer Jack Thompson has responded angrily to what he claims is an attempt by Rockstar to brand him a "sexual pervert".
For several years Thompson has slammed the developer's Grand Theft Auto games for their violent and sexual content, and recently he was a vocal critic of the GTA: San Andreas 'Hot Coffee' mod.
Rockstar has just launched a new website for forthcoming PSP game GTA: Liberty City Stories, which features a spoof email from "JT@CitizensUnitedNegatingTechnology".
"The Internet is an unambiguous evil," the email reads.
"The only things worse than the Internet are computer games and liberals."
"Only last week, I was using the Internet to look up some information for my 15 year old niece, who is a keen water skier and state wide sailor," it continues.
"Trust me when I say this - searching under the subject matter "Teenage girls water sports" is not for the faint hearted."
Those who "really care about our society" are then invited to click on a lick to the Citizens United Negating Technology website, which features testimonials by people who say their lives have been ruined by the Internet, along with advice to "Turn off now before you are sucked into a vortex of shame, drugs and pornography."
Shortly after the website appeared online, US site GamePolitics received an angry email response from Thompson, in which he wrote: "Take-Two/Rockstar has created and paid for an actual Internet website for the purpose of furthering the notion that its most abiding and most effective critic, Jack Thompson, is himself a sexual pervert.
"When you click on the fake email [on the Liberty City Stories site], you will find that JT (Jack Thompson) likes to surf the Internet for pictures depicting deviant sex acts by teenage girls.
"Additionally," Thompson continues, "There is at the site an audio ad featuring a man whose name is "Jack" who is found naked by a mother in her son's room.
"Bisexual paedophile Jack Thompson is the combined message."
Thompson goes on to accuse Rockstar of adopting "The oldest dodge used by the porn industry, first used on Jack Thompson by radio pornographers whom Thompson got fined by the FCC in 1989.
"Jack Thompson can assure the world that the only thing to which he is "addicted" is eating entertainment industry scofflaws for breakfast - and golf."
Rockstar was unavailable for comment at the time of writing.
