Casey Anthony, the Florida mother acquitted in her daughter Caylee's death last month, is the most hated person in America, E-Poll Market Research said.
Of the 53 percent of respondents who were aware of Anthony, 94 percent said they disliked her, E-Poll said.
Spencer Pratt of MTV's "The Hills" came in No. 2 on the list with a dislike rate of 88 percent, followed by "Octomom" Nadya Suleman at 87 percent.
The other celebrities rounding out the Top 10 most hated in America were: O.J. Simpson (85 percent), Jon Gosselin (79 percent), Levi Johnston (75 percent), Jesse James (71 percent), Paris Hilton (69 percent), Heidi Fleiss (69 percent) and Howard Stern (68 percent).
E-Poll said 57 percent of respondents consider Anthony "creepy" -- the second-highest "creepy" score in the polling company's database behind rocker Marilyn Manson.
The survey polled 1,100 people during the first week of August. No margin of error was given.
