Ulliott was associated with the online poker site Devilfish Poker. After being eliminated in third place for $120,000 in the Full Tilt Poker invitational event at the 2005 Monte Carlo Millions, Ulliott stood up, flashing a "www.devilfishpoker.com" sign that was strapped to his back inside his jacket. The event was being broadcast live on Fox Sports Net (FSN), which has a policy against advertising .com websites, and Ulliott was banned from appearing in any forthcoming FSN productions. Ulliott later responded that he only paid the entry money so he could advertise his site; it was originally agreed that he would be able to promote the site, so he decided to advertise his site through the publicity stunt regardless. Despite supporting online poker sites, Ulliott indicated that many online players do not know what they are doing when playing, which makes them harder to play against.
