1. A method in a virtual universe (VU) for identifying spam avatars comprising: providing, using at least one computing device, a VU system comprising one or more avatars that each have behavior characteristics, wherein at least one of the one or more avatars is an automated, non-human operated spam avatar created by an advertiser operating within the VU, and wherein the VU system has memory that stores multimedia characteristics of known spam avatars; executing, using at least one computing device, a Turing test to test the one or more avatars, wherein the Turing test evaluates positional movement of each of the one or more avatars; determining, based on a result of the Turing test, the behavior characteristics of the one of the one or more avatars, wherein the behavior characteristics comprise whether each of the one or more avatars is able to demonstrate human intelligence; retrieving, using at least one computing device, from one of the one or more avatars the behavior characteristics of the one of the one or more avatars; comparing, using at least one computing device, the retrieved behavior characteristics with behavior characteristics of known spam avatars; identifying, using at least one computing device, similarities between the retrieved behavior characteristics with the behavior characteristics of known spam avatars; and identifying, using at least one computing device, the one of the one or more avatars as an automated, non-human operated spam avatar created by an advertiser operating within the VU based upon the identified similarities between the retrieved behavior characteristics of one of the one or more avatars with the behavior characteristics of the known spam avatars.
