16. 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; 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 exceeds the violation threshold, revise the violation threshold upward, wherein a higher 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, 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 upward, until the monitored compliance amount does not exceed the revised violation threshold.

The article of manufacture of claim 16 , wherein the program code further causes the computer system processing unit to: determine the average level of compliance dynamically from a current behavior observation value; and dynamically revise the violation threshold upward in proportion to a difference from the current behavior observation value from a previous behavior observation value.
