Wolfman Productions was using Rockstar's GTA San Andreas logos/trademarks on its webpage promoting Jack Thompson's college detate tour. Jack Thompson is on the record for saying he is out to destroy Rockstar. Rockstar's parent, Take Two, sent a cease-and desist order to Wolfman Productions. Wolfman complied. As of this posting Master Chief, Laura Croft, Doom and Postal images/trademarks/depictions are still on that page.
