ORLANDO, Fla. -

Casey Anthony, who was found not guilty last month of killing her 2-year-old daughter, Caylee, is the most hated person in America, according to a new poll released Wednesday.

The E-Poll Market Research poll found that the 25-year-old was more disliked than Paris Hilton, O.J. Simpson and "Octomom" Nadya Suleman.

Fifty-three percent of those questioned in the poll said they knew of Anthony, and 94 percent of those people said they disliked her.

"The Hills" personality Spencer Pratt came in second in the "total dislike" category. Suleman and Simpson came in third and fourth place, respectively.

E-Poll's E-Score Celebrity poll is conducted weekly, according to its website, ranking more than 6,000 celebrities based on 46 different attributes.

The results released Wednesday are based on research from the first week of August.

Anthony's whereabouts are currently unknown. A judge may force her to return to Orlando to serve probation for her conviction on check fraud charges.

Caylee would have turned 6 years old Tuesday.
