13. An article of manufacture, comprising: a computer readable medium having computer readable program code embodied therewith, the computer readable program code comprising instructions that, when deployed and executed on a computer system processing unit, cause the computer system processing unit to: monitor a behavior of a collective plurality of avatars within a virtual universe environment for compliance with a violation threshold of an avatar behavior rule for the virtual universe environment, and to determine if any of the avatars is complaining that the monitored behavior of another of the avatars is at an objectionable level within the virtual universe environment; determine an amount of compliance of the monitored collective plurality behavior with the rule; compare the determined compliance amount with the violation threshold; if the determined compliance amount does not exceed the violation threshold and any of the avatars is determined to be complaining that the monitored behavior of another of the avatars is at an objectionable level within the virtual universe environment, revise the violation threshold downward, wherein a lower level of the determined compliance amount is required to exceed the violation threshold; and repetitively monitor the behavior of the collective plurality of avatars within the virtual universe for compliance with the rule and to determine if any of the avatars is complaining that the monitored behavior of another of the avatars is at the objectionable level within the virtual universe environment, determine an amount of compliance of the monitored collective plurality behavior with the rule, compare the determined compliance amount with the revised violation threshold, and revise the violation threshold downward, until the monitored compliance amount exceeds the revised violation threshold or none of the avatars is determined to be complaining that the monitored behavior of another of the avatars is at the objectionable level within the virtual universe environment.

The article of manufacture of claim 13 , wherein the program code further causes the computer system processing unit to: select each of the collective plurality of avatars as a function of at least one of: participation in an activity in common with others of the collective plurality; and demographic data associated with a selected avatar correlating to a specified demographic criterion.
